Embodiment 1

[0026] Embodiment 1. This embodiment provides an embodiment of a cornstarch production process. The process mainly includes the following steps: purification, soaking, crushing, curved sieving, separation, dehydration, drying, and packaging.

[0027] Purification step: After passing the inspection, the raw corn is sent to the scraper machine, and sent to the corn drum sieve by the elevator, and some impurities are screened out, and sent to the corn storage bin by the elevator through the conveyor belt for corn soaking.

[0028] Soaking step: Open the discharge valve of the corn silo, start the corn conveyor belt, the corn is transported to the vibrating screen through the conveyor belt, and then transported to the corn mixing tank and mixed with thin corn syrup at a ratio of 1:3, and pumped into the soaking tank. After the corn in the tank is full, soak the newest corn with the oldest slurry, soak the old corn with sulfurous acid solution, and carry out self-circulation. When t...

Embodiment 2

[0039] Embodiment 2: present embodiment provides another kind of embodiment of this cornstarch production technique:

[0040] This embodiment is carried out in the same manner as in Example 1, except that the dehydration steps are as follows: after the decanter centrifuge drum and screw conveyor are started to full speed, the flow rate of water-containing starch milk is 20t / h, and enters the screw conveyor from the feed port Inside, under the action of centrifugal force, starch milk enters the drum through the feed hole in the barrel of the screw conveyor, and the starch with a larger specific gravity is deposited on the wall of the drum and forms in the drum (drum speed is 3600r / min). A ring-shaped starch layer, under the action of the differential, the screw conveyor makes a constant differential speed (100r / min) between the screw and the drum, and pushes the dehydrated starch milk out from the starch outlet, and the clarified liquid (starch-containing The amount is 3Be) ove...

Embodiment 3

[0044] Embodiment 3: present embodiment provides another kind of embodiment of this cornstarch production technique:

[0045] This embodiment is carried out in the same manner as in Example 1, except that the dehydration steps are as follows: after the drum of the decanter centrifuge and the screw conveyor are started to full speed, the water-containing starch milk flow rate of 5t / h enters the screw conveyor from the feed port, Under the action of centrifugal force, the starch milk enters the drum through the feed hole in the barrel of the screw conveyor, and the starch with a larger specific gravity is deposited on the wall of the drum, forming a ring in the drum (the drum speed is 3600r / min). The starch layer, the screw conveyor under the action of the differential, makes the screw and the drum produce a constant differential speed (85r / min), pushes the dehydrated starch milk from the starch outlet, and the clarified liquid (containing starch 3Be) Spilled from the overflow.

Abstract

The invention belongs to the field of food processing process, and relates to a corn starch production process. The corn starch production process mainly comprises the following steps of: purifying; soaking; crushing; screening; separating; dehydrating; drying; packaging. Compared with the prior art, the corn starch production process disclosed by the invention has the advantages and beneficial effects of applying a horizontal screw centrifuge to the corn starch production process by utilizing the characteristic of continuous dehydration of the horizontal screw centrifuge to substitute for the traditional horizontal scraping knife centrifuge, thereby enhancing the yield of starch; in addition, the starch produced through the integral process is fine, fewer in impurity, thorough in separation and good in quality.

Description

technical field [0001] The invention belongs to the field of food processing technology and relates to a corn starch production technology. Background technique [0002] At present, in the starch production process currently used in China, a horizontal scraper centrifuge is used to dehydrate the refined starch milk in the process of dehydrating the refined starch milk. The horizontal scraper centrifuge is a filter centrifuge with continuous operation and intermittent operation, mainly The centrifugal force generated when the rotating drum drives the material in the drum to rotate at a high speed is used to separate two kinds of liquids with different densities and immiscible liquids from the suspension of solid particles. During the operation of the horizontal scraper centrifuge, the processes of feeding, separating, washing, dehydrating, unloading and filter cloth regeneration are generally completed at full speed. The single cycle time is short, the processing capacity is ...
