    11, the invention relates to a drying technique, namely, apparatus for drying aqueous, heat sensitive protein suspensions in a fluidized bed. The known dryer for solutions and suspensions contains a chamber equipped in the upper part with a nozzle for supplying a drying material and a collector for removing the exhaust gases, and in the lower part a gas distribution grid for finishing the granules in a fluidized bed, and the nozzle is enclosed in a cylindrical cup, on the outer periphery of which a collector is placed, made in the form of an LI 1 ring duct. A disadvantage of the dryer is the unsatisfactory intensity of the drying process. A known dryer for liquid materials contains a chamber with a gas distribution grid, under which a box for supplying a low-temperature heat transfer fluid is located, and at least one nozzle for supplying a material to be dried, located in a grate and disconnected to a collector of a high-temperature heat transfer fluid located under the heat sink. ; the holes in the grate are filled with a diameter increasing with distance from the nozzle, moreover, when two or more nozzles are installed, the holes are installed; in the grate are made with a diameter increasing to half the distance between adjacent 2X nozzles. The disadvantages of this suction are the uneven distribution of the material on the grate and the unsatisfactory conditions for unloading the dried material. The closest to the invention in terms of the mechanical essence and the achieved result is an apparatus for drying water. protein suspensions in the fluidized bed, containing a cylindrical conical chamber with a conical gas distribution grid, with the top pointing downwards with a slope forming minutes to the horizontal at an angle not more than 20, a spray nozzle for introducing the suspension and connected to the top of the discharge pipe lattice wire with the section feeder and the air supply pipe WS1. The disadvantage of the apparatus. is the difficulty of unloading dried suspensions. The aim of the invention is to simplify the discharge conditions. This goal is achieved by the fact that, in an apparatus for drying aqueous protein suspensions in a fluidized bed, containing a cylindrical conical chamber with a conical gas distribution grill, with its top facing downwards and tilted to the horizontal at an angle of not more than 20 °, the spraying nozzle for introducing the suspension and connected to the top the grating is a discharge pipe with a sectional feeder and an air inlet, the grate is made with a flow section increasing smoothly or stepped from the center to the periphery from 3 to 25%, and the discharge dressing conduit formed composite, consisting of two parts interconnected through a bushing mounted for vertical Move Prices. With a decrease in the ratio of the bore area of less than 3%, the gas distribution grid holes are blocked, and at a ratio of more than 25%, the stable vibro boiling mode is stopped. FIG. 1 shows an apparatus for drying aqueous protein suspensions in a fluidized bed, longitudinal section; in FIG. 2 is a diagram of the variation in the flow area of the gas distribution grid; in fig. 3 - unit unloading dried suspensions. The apparatus for drying aqueous protein suspensions in a fluidized bed contains a cylinder-conical chamber I, a conical gas distribution grid 2, which faces vertically downwards with a slope of horizontal lines at an angle of not more than 20 °, a spray nozzle 3 for introducing a suspension, a discharge pipe 4 with a sectional feeder 5 and a branch pipe 6 air supply, pipe 7 for supplying air under the gas distribution grid, a sleeve 8 installed on the discharge pipe 4 with the possibility of vertical movement and connecting the top and izhnyuyu portion thereof, a dried pellet 9 protein slurry. 3 The apparatus for drying aqueous protein suspensions in a fluidized bed is as follows. The aqueous protein suspension is supplied by means of a dispenser, not shown in chamber 1 through the nozzle 3 to the gas distribution grid 2, under which air is supplied. Depending on the flow area of the gas distribution grid, which varies from 3 to 25%, different air flow rates occur. The smallest protein particles (granules), which are formed during the drying process, get into the upper part of the fluidized bed and are sprayed with the aqueous protein suspension again coming from the nozzle 3. The wetted granules return to the gas distribution grid, fall under the action of hot air and move to the periphery of the grid, and then again carried upwards. Due to the variable gas distribution grid from 3 to 25%, its slope and air velocity, decreasing from the periphery to the center, large granules fall into the center of the lattice, where the discharge pipe 4 is located, through which air is additionally supplied with different temperatures and speeds adjustable by the sleeve 8, from the pipe 7 and through the gaps between the top of the discharge pipe and the sleeve 8. Since the speed of the pellets falling into the discharge pipe 4 nprf constant speed is air Since the flow depends on the diameter of the granules, all protein granules that have reached a certain diameter are lowered into the discharge pipe 4 and removed from it by a sectional feeder 5 from chamber 1. The granules that have not reached a certain diameter are captured by the air flow in the discharge pipe 4 and return to fluidized bed. The air supplied from the pipe 7 under the gas distribution grid 2 may have the same temperature as the air in the discharge pipe 4, but not exceed 200 ° C. If cold air is supplied to the discharge pipe, then the process of cooling the pellets takes place in it. The proposed apparatus for drying aqueous protein suspensions will simplify the conditions for unloading.
