    The present invention relates to a stirrer for a mixing tank for fluids, in particular a hydrolysis tank for enzymatic hydrolysis of proteins, as stated in the preamble of claim 1.
    Background
    The starting point for the invention is related to the processing of organic raw material from fish, birds and land-based animals for the production of refined fats and oils, proteins and collagen for use in cosmetics or foodstuffs. Such organic raw material can be by-products from the poultry industry, by-products from the meat industry or by-products from the fishing industry.
    An example of such a process is described in NO 320736 B1 with the same inventor as the present invention. As other examples from the prior art, mention may be made of WO 2004 071202 and WO 2004 006845. This process involves a step of enzymatic hydrolysis of proteins in an aqueous solution in a hydrolysis tank. Such a hydrolysis tank for enzymatic hydrolysis of an aqueous solution of the organic raw materials is described in NO 321014 B1 with the same inventor as the present invention.
    A disadvantage of the prior art, however, is that the processes can lead to deterioration of the protein products in that bitter taste arises from shortening of the amino acid ends in the proteins due to long processing time. To avoid this, one has had to reduce the residence time in the hydrolysis tank. As a result, raw material utilization and production capacity are limited compared to what would have been desirable.
    Purpose
    Accordingly, one object of the invention is to provide a stirrer in such a hydrolysis tank which provides shorter processing time by enzymatic hydrolysis of proteins. Another object of the invention is to provide such a stirrer in which high quality proteins without bitter taste can be produced.
    The invention
    These objects are achieved with a stirrer according to the characterizing part of claim 1. Further advantageous features appear from the dependent claims.
    The invention solves these objects with a new agitator which is arranged to be mounted in a hydrolysis tank in a processing plant for processing organic raw materials from fish, poultry and land-based animals for the production of oil, proteins and collagen. The new agitator is arranged to
    DK 2016 00524 A1 rotate inside the hydrolysis tank and create a more efficient agitation than has been achieved so far, and as a result offer enzymatic hydrolysis of a toxic volume of organic raw material in a shorter period of time and without the formation of bitter taste on proteins and without reduced raw material utilization.
    While the agitator is particularly related to use in a hydrolysis tank for enzymatic hydrolysis of proteins, the invention is not limited thereto. The agitator's effective mixing function can also be utilized in other processes where efficient mixing is sought.
    Definitions
    The term "shaft" means the bonding point of the agitator between the propellant and the agitator blade. The shaft may be an axially directed shaft projecting down from a drive at the top of the tank and down towards the female of the tank and is arranged to rotate about a substantially vertically projecting longitudinal axis. The shaft can protrude all the way down to the female or only a short distance down into the tank, whereby the stirring blades are attached to a framework. The bonding point between the drive and the agitator blade may alternatively be another type of construction, for example a housing or a ring connected to the drive.
    By "longitudinal axis" is meant the longitudinal axis of the shaft when it is mounted in the tank. This term is also used to denote the axis of rotation of the agitator when mounted in the tank.
    By "guide blade" is meant here means which ensure that the bulk phase in the tank is set in motion during rotation of the agitator.
    By the term "agitator wing" is meant a separate part of the agitator arranged a distance radially out from the longitudinal axis of the shaft. The stirrer wing serves primarily as a fastening member for the baffles, but can also itself serve as a stirrer blade or guide blade.
    By the term "subsequent agitator blade" is meant here a given agitator blade arranged after another agitator blade seen in the direction of rotation of the agitator.

    DK 2016 00524 A1
    Referring now to Figure 1, a simplified flow chart is illustrated of a process for producing pure fractions of fat and oil, water-soluble proteins and insoluble proteins by enzymatic hydrolysis of organic raw material from fish, birds and land-based animals. The process indicated generally by reference numeral 100 where raw material indicated by 101 is fed to one or more hydrolysis tanks 102a, 102b, each of which is provided with heating means, agitators and transport screws. An example of such a hydrolysis tank can be obtained from the above-mentioned patent publication NO 321014 B1. The hydrolysis tank is supplied with water and enzymes (not illustrated) together with the organic raw material, after which the contents are heated for a period of time with stirring and cause hydrolysis of the organic raw material. Grease and oil are collected in a topsheet and removed in conduits 104a, 104b and further via collecting conduits 104 to an oil separator 105. A middle layer of water-soluble proteins is removed from hydrolysis tanks 102a, 102b and passed to a filter 103 to remove rejects in the form of solid particles. The filtered liquid with water-soluble proteins is then passed to a hydrolyzate separator 108 and on to a clarification tank 109a, 109b where the collagen is taken out as a solid fraction (not illustrated) and the protein solution is passed via buffer tank 110a, 110b to an evaporator 111 for protein enrichment. . Water-insoluble proteins, bone remains and the like are removed from the bottom of hydrolysis tanks 102a, 102b by means of a screw. A more detailed description of this process can be obtained from the above-mentioned patent publication NO 320736 B1.
    An example of such a hydrolysis tank 102 is shown in Figure 2 with a motor 201 placed on top of the tank 102 to drive a stirrer described in more detail below.
    Figure 3 shows a stirrer 200 according to the present invention. A vertically projecting shaft 202 is connected to a drive motor (201 in Figure 2), arranged to rotate the agitator 200 about the shaft 202. Three agitator vanes 203a, 203b, 203c each comprise a substantially vertically projecting first strut 208 arranged in the periphery of the agitator 200 and a second substantially vertically projecting second strut 209 arranged at a distance towards the longitudinal axis of the shaft 202. The struts preferably have a surface which projects radially towards the longitudinal axis of the shaft 202, so as to contribute to agitation of the bulk phase in the tank. Each agitator blade is fixedly connected to the shaft 202 by means of a frame 204a, 204b, 204c, 207.
    Each stirring wing 203 is further provided with three baffles 205a ', 205a, 205a'; 205b ', 205b, 205b'; 205c ', 205c, 205c' for the respective stirring vane 203a, 203b and 203c. The baffles are preferably elongate with longitudinal ends attached to the first strut 208 and second struts 209, respectively.
    The first (upper) 205a 'of the three baffles of the first agitator wing 203a is attached to the agitator vane at a first height Ha'. The second (middle) baffle 205a in the first stirrer wing
    DK 2016 00524 A1
    203a is attached at a second height Ha lower than the first height Ha 'and leaves a space between the first 205' and the second 205 baffle through which liquid can flow. The third (lower) 205 'baffle plate is attached at a third height Ha' lower than the second height Ha and leaves a space between the second 205 and third 205 'baffle plate through which liquid can flow. Attached to the lower end of each agitator vane 203a, 203b, 203c is a scraper blade 206a, 206b and 206c, respectively, which is arranged to scrape along the bottom of the hydrolysis tank. The third baffle plate 205a 'attached to the height Ha' is located above the scraper blade 206a and correspondingly forms a space in between where water can flow through.
    In a manner similar to the first stirrer 203a, the respective baffles 205b ', 205b and 205b' of the second stirrer 203b are mounted at respective heights Hb ', Hb and Hb' which are different (higher) than the respective heights Ha ', Ha and Ha 'in the first stirrer 203a.
    In a manner similar to the first and second agitators 203a and 203b, the respective baffles 205c ', 205c and 205c' of the third agitator 203c are mounted at respective heights Hc ', Hc and Hc' which are different (higher) from the respective heights. Hb ', Hb and Hb' in the other.
    This height arrangement of the baffles 205 in the respective stirring vanes 203 is shown in particular in Figures 5a, 5b and 5c.
    Further, ledeplatene 205a ', 205a and 205a' of the first stirring blade 203a vridd in a first angle A with the horizontal plane about an axis projecting hovedsakelig radially with respect to the shaft 202 rotasjonsakse, candies to ledeplatene 205 during rotasjon AV røreverket 200 defines an oblique tilt flate . The liquid in the tank will thus meet the raft of the baffle 205 in a direction of flow obliquely to the raft of the baffle 205. This raft of the baffle 205 may be the underside or top of the baffle 205, depending on which direction the baffle 205 is rotated with respect to the agitator 200 about the axis of rotation. 202.
    The size of the angle α can vary depending on various factors, such as the calculated rotational speed of the agitator, the number of agitator blades and the distance between them. Examples of angular magnitudes are 10-80 °, such as 30-60 °, especially mainly 45 °.
    The baffles 205b ', 205b and 205b' of the second agitator 203b are, in a manner similar to that described for the first agitator 203a, rotated at a second angle ab with the horizontal plane, and the baffles 205c ', 205c and 205c' of the third agitator 203c is rotated at a third angle a c with the horizontal plane.
    DK 2016 00524 A1
    The angles a a , a b and a c in the illustrated embodiment have substantially the same size relative to the horizontal plane, but in a preferred embodiment alternate signs so that the liquid in the hydrolysis tank 200 will hit the underside of the baffles in one agitator and the top of the baffles in the subsequent agitator. seen in the direction of rotation of the agitator 200.
    The arrangement with baffles 205 arranged at different heights between respective stirring vanes and preferably at alternating angles of inclination between successive stirring vanes, ensures to set up a particularly effective mixing effect where essential parts or substantially all parts of the bulk phase are set in motion.
    As a result, the hydrolysis process can be carried out in a shorter time so as to avoid shortening of the ends of the amino acids and consequently avoiding the formation of bitter taste on the collagen. The agitator offers an efficient mixture and leaves no shadow sides or pockets in the bulk phase that is stirred.
    In other words, the agitator according to the invention offers a faster processing of the organic raw material and provides end products with higher quality without compromising efficiency (raw material utilization) or capacity.
    Modifications
    The number of agitator blades may differ from three, for example 2 or 4. The baffles do not need to be fixed in a fixed position to the agitator blade and may be provided with propellants which can batchwise or continuously change the angle of rotation of the plate, alone or synchronously with the remaining baffles. Each stirring wing is illustrated with three baffles, but the invention is not limited to this, and the number of baffles each stirring wing can be, for example, two or four. Furthermore, the distance between the baffles in a stirrer wing can be mutually different. While the baffles are illustrated as generally elongate baffles attached with their longitudinal ends to the stirrer, the baffles may also be square or attached with their short sides to the stirrer.
