This goal is achieved by the fact that __ the plant is equipped with a precipitation centrifuge for dehydration of the pulp and mixing it with the potato cell juice, the casing of which has a nozzle for supplying cell juice, strengthened against the discharge windows of the dehydrated rotor pulp. At the same time, the device for filtering the hydrolyzate contains a precipitation centrifuge and an arc sieve connected by pipelines with evaporation apparatuses and a collector of the mixture of pulp with the cellular juice of potatoes.

In FIG. 1 schematically shows the proposed installation; in FIG. 2 node precipitation centrifuge with nozzles for supplying cell juice.

The installation includes a precipitation centrifuge 1 for dehydration of the pulp and mixing it with the cellular juice of potatoes, the casing .2 of which has a nozzle 3 for supplying cell juice, mounted against the discharge windows 4 of the dehydrated rotor pulp, a collector with a stirrer 5 located under the centrifuge 1, pump 6 s suction 7 and pressure 8 nozzles, boil-off 9, evaporator 10, hydraulic unit 11, pump 12, saccharifiers 13, pump 14 and a hydrolyzate filtering device containing a precipitation centrifuge 15 and a pressure arc sieve 16. The pump 17 is connected to the nozzle gathering coagulating liquid centrifuge 15 and the arcuate sieve 16, and a thick window vanishing unloading auger s.pomoschyu centrifuge 15 18 - 19 with a dryer.

The nozzle of the dense vanishing of the arc sieve 16 is connected by a pipeline 20 to the collector with a mixer 5, and the nozzle of the liquid vanishing of the first is pump 21 and the pipe 22 with evaporators ⁵ .

Installation works as follows.

The pulp with a moisture content of 95% from a sieve, θ potato-starch production ^and production station is fed to a precipitation centrifuge 1. At the same time, cell juice is fed through the nozzle 3 to the discharge windows 4. Under the action of the shock-cutting forces of the rapidly rotating rotor, the destruction of the cell juice foam with the pulp occurs. The mixture of pulp with cell juice enters the collector with a stirrer 5, from where it is sent by pump 6 to the boil-off 9, where it is heated up to 110-120 ° С, thereby achieving the necessary sterility of the medium, as well as the maximum coagulation of protein substances of the cell juice and pulping of the pulp . 25

From the squeegee 9, the mixture is sent to the evaporator 10, where it is cooled due to self-evaporation to 62-64 ° C. From the evaporator 10, through the water trap 11 by the pump 12, the educt mixture is fed into saccharifying containers 13. To saccharify the mixture, an enzyme, for example, malt, is introduced in the form of a suspension in the tank 13 and kept there for 1-2 hours. The saccharified mass is pumped to 14 on sedimentation Dent- ³ rifuge 15 for separation into a filtrate and sediment. The precipitate (protein feed) is sent to a dryer 19, where it is dried to a moisture content of 10%, and the filtrate is placed on an arc sieve 16 to separate 40 suspended particles, which are then returned through a pipe 20 to a collector with a mixer 5. The filtrate after an arc sieve 16 by a pump 21 through a pipeline 22 are fed to evaporators 23 of boiling data until the solids content is about 50%, obtaining a carbohydrate-protein hydrolyzate.

^ The proposed installation allows you to dispose of potato starch production waste products to produce finished products: carbohydrate-protein hydrolyzate and protein feed, while the dry substances of the raw material (potato) are used to the maximum and environmental pollution is eliminated, which, in turn, reduces the cost of wastewater treatment. In addition, the economic effect will amount to 83.3 thousand rubles.
