Description
Technical Field

Background Art
[0002] Dephenolized cottonseed protein is a product extracted from cottonseed. The extraction process is to remove the cottonseed fluff, shell, extract the oil at low temperature and then desolventize to make a high-protein product. The dephenolized cottonseed protein produced is widely used in the feed industry and its deep processing field. Desolventization becomes an important step in the production process of dephenolized cottonseed protein, and this process can be operated by physical extrusion equipment.
[0003] In the existing production technology, high-temperature evaporation is used to extract solvents from dephenolized cottonseed protein. This process may lead to changes in the amino acid structure, thereby affecting the nutritional value of dephenolized cottonseed protein. Although dephenolized cottonseed protein contains rich and balanced amino acids, under high temperature conditions, amino acids may undergo chemical reactions such as desulfurization, deamination, decarboxylation, isomerization and hydrolysis, and sometimes even produce toxic substances. After searching for this problem, some companies have conducted innovative research on the processing technology of dephenolized cottonseed protein. By optimizing the process to reduce the solvent content in the extracted material and reducing the temperature during the drying process, the nutritional value of the product is effectively improved, and energy consumption, including steam use and solvent recovery, is greatly reduced. However, there are still some limitations, which include but are not limited to: the complexity of the process flow increases, resulting in increased operating difficulty and increased production costs; some optimization measures may have higher requirements for equipment, increasing equipment investment and maintenance costs; in addition, despite the reduction in drying temperature, there is still room for improvement to further reduce the potential impact of heat treatment on the quality of dephenolized cottonseed protein.

[0015] Preferably, the method for using the novel dephenolized cottonseed protein physical extrusion desolvation production equipment comprises the following steps:
[0016] S1: The device enters the dephenolized cottonseed protein containing solvent through the feeding device.

The dephenolized cottonseed protein containing solvent is conveyed into the filter screen cylinder.

[0017] S2: The baffle of the feeding device is pressed down to block the feeding. The main cylinder starts to move down quickly, driving the pressing block to move down. The pressing block squeezes the dephenolized cottonseed protein containing the solvent. The separated solvent flows to the solvent bin through the sieve holes of the filter screen and the filter holes of the sieve plate on the sliding plate. The main cylinder reaches the set pressure value and moves down slowly until the maximum pressure is maintained. When the set time is reached, the main cylinder slowly releases the pressure by 0.5 meters. The auxiliary cylinder receives the main cylinder rising signal and starts to contract. The auxiliary cylinder drives the sliding plate backward. The main cylinder receives the auxiliary cylinder contraction signal and starts to rise, pushing the dephenolized cottonseed protein squeezed out of the solvent into the lower bin. The main cylinder is fully extended to complete the pushing action. The auxiliary cylinder receives the main cylinder fully extended signal and starts to rise. The main cylinder contracts to the initial position, the feeding device is subjected to force, the connecting rod is lifted, and the cover of the feeding device is opened. At this time, the main cylinder, the auxiliary cylinder and the feeding device are all in the initial state.
[0018] S3: The pump of the flushing device starts to work, and the solvent is sprayed from the flushing nozzle to the top of the briquette. The residual dephenolized cottonseed protein remaining on the briquette and the filter screen wall is flushed under high pressure and flows down through the residue holes to the solvent bin. Part of the dephenolized cottonseed protein flows to the bottom through the inner wall of the filter screen and waits for the next extrusion. The above actions are completed, which is a production process.
[0019] The present invention provides a novel production equipment for physical extrusion desolventizing of dephenolized cottonseed protein and a method for using the same. Compared with the prior art, the present invention has the following beneficial effects:
[0020] (1) The present invention effectively reduces the production temperature in the cottonseed protein production process through physical extrusion technology. Compared with the traditional high-temperature evaporation method, the present method significantly reduces the changes in amino acid structure that may occur under high temperature conditions, such as desulfurization, deamination, decarboxylation and other chemical reactions, thereby better retaining the nutrients in the cottonseed protein and improving the nutritional value of the final product.
[0021] (2) By physically squeezing out the solvent liquid, the energy consumption in the material depilation process is greatly reduced, especially the use of steam. This not only reduces production costs, but also reduces energy consumption, which is in line with the sustainable development concept of energy conservation and emission reduction.
[0022] (3) The filtration system design of the present invention realizes efficient separation of solid and liquid, improves production efficiency, and reduces tail gas emissions, meets environmental protection standards, and provides an environmentally friendly production method for production enterprises.
[0023] (4) The design of the flushing system of the present invention ensures the thorough cleaning of residual materials after extrusion, thereby ensuring the service life of the equipment and improving the market competitiveness of the product.
[0024] (5) The extrusion mechanism of the present invention adopts a two-level sealing design, which effectively prevents the leakage of solvents and gases and improves the safety performance of the equipment. At the same time, this design improves the long-term operating reliability of the equipment and reduces maintenance costs.
[0025] (5) The equipment of the present invention has simple operation steps and is easy to realize automatic control, which reduces manual intervention and improves the overall operation efficiency and safety of the production line. BRIEF DESCRIPTION OF THE DRAWINGS
