Description

Technical Field

[0001] The invention relates to the technical field of plant protein processing, and in particular to a high-protein and efficient physical desolventizing device for dephenolized cottonseed. Background Art

[0002] Dephenolized cottonseed protein is a high-protein product made from cottonseeds that have been delinted, shelled, and extracted for oil at low temperature, and then the toxic substance cottonphenol has been removed. During the production process, high temperature will cause changes in the structure of amino acids, such as desulfurization, deamination, decarboxylation, isomerization, hydrolysis, etc., and sometimes even accompanied by the production of toxic substances, resulting in a decrease in the nutritional value of food; at the same time, it will denature the protein, and after the protein is denatured, it will lose its original solubility and thus lose its physiological function. The denaturation and coagulation of protein is an irreversible process. Based on the current development and research of the dephenolized cottonseed protein processing technology of Xinjiang Chengrun (Herun) Jinlan Plant Protein Co., Ltd., reducing the solvent in the extracted material and reducing the drying temperature can improve the nutritional value of dephenolized cottonseed protein. Summary of the invention

[0003] The purpose of the present invention is to provide a high-protein physical desolventizing device for dephenolizing cottonseed to solve the problem that high temperature causes the structure of amino acids to change, thereby reducing the nutritional value of food.

[0004] To achieve the above-mentioned purpose, the basic scheme provided by the present invention is: a high-protein and efficient physical desolventizing device for dephenolizing cottonseed, comprising a main frame, a feed port is provided at the upper end of the main frame, a discharge port is provided at the lower end of the main frame, a planetary reducer is provided at one end of the main frame, the planetary reducer is connected to a hydraulic station, the planetary reducer is connected to an auger shaft, and a screen cylinder is provided on the outside of the auger shaft.

[0005] The principle and beneficial effects of the present invention are as follows: the hydraulic station provides power, and the speed is reduced by a planetary reducer, so that the maximum speed of the auger shaft reaches 15r / min. The speed of the equipment can be adjusted through frequency conversion speed control. The material enters the equipment from the feed port through the auxiliary conveying equipment. The material is continuously squeezed during movement under fully sealed conditions to squeeze out the solution in the cotton seeds. The squeezed material enters the dryer through the discharge port for drying, thereby reducing the amount of steam used.

[0006] Solution 2, which is the preferred solution of the basic solution, is that a gear box is connected between the planetary reducer and the auger shaft, and the gear box connects the two auger shafts, so that one power controls the two auger shafts.

[0007] Scheme 3 is the preferred basic scheme. The auger shaft is a variable diameter shaft from coarse to fine, and the auger disc on the auger shaft is a variable pitch auger disc with a pitch from small to large. The variable diameter and variable pitch auger shaft gradually increases the extrusion force on the material during movement, further improving the extrusion rate of the solution.

[0008] Solution 4 is the preferred basic solution. Several inspection windows are provided on the main frame, and observation mirrors are provided on the inspection windows. During the operation, the operation of the equipment can be observed in real time through the observation mirrors. If a fault occurs, the feed, discharge and exhaust valves can be disconnected, and the inspection windows can be opened to carry out maintenance under the premise of ensuring safety.

[0009] Solution 5, which is the preferred basic solution, is provided with a liquid collecting hopper at the lower end of the main frame, and the liquid collecting hopper is connected to the stock liquid storage tank through a centrifugal pump. The squeezed liquid enters the liquid collecting hopper through the screen cylinder, and the collected liquid is transported to the stock liquid storage tank through the centrifugal pump and can be reused.

[0010] Solution 6, which is the preferred basic solution, has a flushing pipe at the upper end of the main frame, which is directly opposite to the screen cylinder. During the operation of the equipment, the screen cylinder can be flushed through the flushing pipe to prevent the screen cylinder from being blocked.

[0011] Solution 7, which is the preferred basic solution, is provided with an exhaust port on the upper surface of the main frame, the exhaust port is connected to a condenser, and the condenser is connected to the stock liquid storage tank. The heat generated by the operation of the equipment will cause part of the solution to volatilize, and the volatilized solution is introduced into the condenser through the exhaust port for recycling.
