Problems solved by technology

However, this drying method requires high technology and equipment, and has the disadvantages of high energy consumption and difficulty in large-scale production.
[0007] In view of the disadvantages of difficult solvent recovery, low production efficiency and high production cost in the existing corn gluten drying technology, and considering the high adhesion and variability characteristics of corn gluten products in the drying process, there is an urgent need for a low operating cost and solvent recovery. Easy, safe and efficient new equipment and method for corn protein drying

Embodiment 1

[0044] First start the drum scraper drying equipment and adjust the speed to 0.8r / min. Start the steam supply equipment, adjust the steam pressure to 0.20MPa, and preheat the main box. Secondly, start the water jet pump equipment and adjust the vacuum degree of the box to 0.001MPa. Open the liquid inlet system and adjust the flow rate to 0.8L / min. The volume percentage concentration of the corn protein extract is 22%, and the extract enters the distribution groove 8 obliquely above the back of the main cylinder 7 through the feed pipe 4, and is evenly distributed on the surface of the rotating main cylinder 7 after flowing out from the distribution groove 8 . The circulating steam generated by the steam supply system 15 is transported to the inner wall of the main cylinder 7 through the hot steam inlet pipe 16, and then flows back to the steam supply system 15 through the cold steam discharge pipe 17; the corn protein extract rotates with the main cylinder 7 and is evenly dr...

Embodiment 2

[0047] First start the drum scraper drying equipment and adjust the speed to 1.2r / min. Start the steam supply equipment, adjust the steam pressure to 0.25MPa, and preheat the main box. Secondly, start the water jet pump equipment and adjust the vacuum degree of the box to 0.002MPa. Open the liquid inlet system and adjust the flow rate to 1.3L / min. The volume percentage concentration of the corn protein extract is 20%. The extract enters the distribution groove 8 obliquely above the back of the main cylinder 7 through the feed pipe 4, and is evenly distributed on the surface of the rotating main cylinder 7 after flowing out from the distribution groove 8. . The circulating steam generated by the steam supply system 15 is transported to the inner wall of the main cylinder 7 through the hot steam inlet pipe 16, and then flows back to the steam supply system 15 through the cold steam discharge pipe 17; the corn protein extract rotates with the main cylinder 7 and is evenly dried...

Embodiment 3

[0050] First start the drum scraper drying equipment and adjust the speed to 1.5r / min. Start the steam supply equipment, adjust the steam pressure to 0.30MPa, and preheat the main box. Secondly, start the water jet pump equipment and adjust the vacuum degree of the box to 0.002MPa. Open the liquid inlet system and adjust the flow rate to 1.8L / min. The volume percentage concentration of the corn protein extract is 25%, and the extract enters the distributing groove 8 obliquely above the back of the main cylinder 7 through the feed pipe 4, and is evenly distributed on the surface of the rotating main cylinder 7 after flowing out from the distributing groove 8 . The circulating steam generated by the steam supply system 15 is transported to the inner wall of the main cylinder 7 through the hot steam inlet pipe 16, and then flows back to the steam supply system 15 through the cold steam discharge pipe 17; the corn protein extract rotates with the main cylinder 7 and is evenly dr...

Abstract

The invention provides a continuous dry drum zein drying device and method. The device comprises a main box body system, a feeding system, a drum scrapper blade drying system, a steam feeding system, a cooling discharging system, a condensing system, a water injection pump system and a control system; the cooling discharging system is used for discharging through a two-stage air closer, so that the air in the environment can be prevented from entering a main box body to the greatest extent, the constant vacuum degree of the main box body can be remained, and as a result, a vacuum system can be sealed; meanwhile, ethanol can be efficiently recovered, and the production cost and potential risk can be reduced.

Description

technical field [0001] The invention relates to a food drying equipment and method, in particular to a vacuum drum drying equipment and method for corn gluten. Background technique [0002] Corn protein is the main storage protein of corn, accounting for 44-79% of the total protein. Due to its nitrogen imbalance and poor water solubility, it cannot be eaten directly; however, corn protein has excellent hydrophobicity and film-forming properties, and can be used for edible Packaging, cosmetics, drug coating and other fields have broad market prospects and application value. [0003] As a kind of alcohol-soluble protein, corn protein is usually extracted with ethanol solution in industrial production, and then the extract is dried to finally obtain corn protein product. At present, the commonly used corn protein drying methods include drum drying, vacuum drying and spray drying. However, there are some shortcomings in the existing drying methods. [0004] The drum drying me...
