Problems solved by technology

[0002] In the wet production process of corn starch, most of them adopt the "open-loop downstream" process route. This technology has low product yield, large auxiliary water consumption, and 10m of wastewater to be discharged and treated. 3 More than / ton of dry starch, the cost of sewage treatment is high, the steam consumption is serious, and it is easy to cause environmental pollution

Embodiment 1

[0016] Its technical process of starch production without waste technology of the present invention is:

[0017] Corn→purification→transportation: use corn soaking water, that is, corn slurry to transport, the delivery speed is 0.9m / s, the delivery temperature is 35°C, the ratio of corn: thin corn slurry is 1:2.5→soaking: use 0.15% Sulfurous acid concentration soaking for 72 hours, soaking temperature 48°C → corn crushing: germ washing water and gluten clarified water, water temperature 35°C → germ separation: germ washing with gluten clarified water → fine grinding: fiber washing water → fiber separation : Gluten clarified water for fiber washing → protein separation: gluten water is separated, starch washing water also enters this post for protein separation → starch washing: 12-stage cyclone washing, with fresh water, the water temperature is 40 ℃) → starch Milk→Commercial starch.

Embodiment 2

[0019] Its technical process of starch production without waste technology of the present invention is:

[0020] Corn→purification→transportation: use corn soaking water, that is, corn slurry to transport, the delivery speed is 1.0m / s, the delivery temperature is 38°C, the ratio of corn: thin corn slurry is 1:2.8→soaking: use 0.25% Sulfurous acid concentration soaking for 65 hours, soaking temperature 49 ° C → corn crushing: germ washing water and gluten clarification water, water temperature 38 ° C → germ separation: germ washing with gluten clarification water → fine grinding: fiber washing water → fiber separation : Gluten clarified water for fiber washing → protein separation: gluten water is separated, starch washing water also enters this post for protein separation → starch washing: 12-stage cyclone washing, with fresh water, water temperature is 38 ℃) → starch Milk→Commercial starch.

Embodiment 3

[0022] Its technical process of starch production without waste technology of the present invention is:

[0023] Corn→purification→transportation: use corn soaking water, that is, corn slurry to transport, the delivery speed is 1.1m / s, the delivery temperature is 40°C, the ratio of corn: thin corn slurry is 1:3.0→soaking: use 0.35% Sulfurous acid concentration soaking for 60 hours, soaking temperature 50°C → corn crushing: germ washing water and gluten clarification water, water temperature 40°C → germ separation: germ washing with gluten clarification water → fine grinding: fiber washing water → fiber separation : Gluten clarified water for fiber washing → protein separation: gluten water is separated, starch washing water also enters this post for protein separation → starch washing: 12-stage cyclone washing, with fresh water, the water temperature is 42 ℃) → starch Milk→Commercial starch.

Abstract

This invention provides a technology of starch production without waste, belonging to water and energy-saving technology in the production of starch, and its process is: corn-> purification -> transportation immersion -> breaking into pieces -> corcle separation -> fine grinding-> fiber separation -> protein separation -> starch washing -> starch milk -> starch for commodity. The process mainly uses the advanced ''ring closure and countercurrent'' new technology with simple technology, saving investment, simplicity, and other characteristics, the technical water are that of process instead of previous one-time water to reduce water consumption and save energy significantly. The usage of water is only in the final process with quantified control, thus it increases the yield of products and by-products, makes the total dry corn yield increase 3%-5%.

Description

(1) Technical field [0001] The invention relates to a water-saving and energy-saving technology in starch production technology, in particular to a non-waste technology for starch production. (2) Technical background [0002] In the wet production process of corn starch, most of them adopt the "open-loop downstream" process route. This technology has low product yield, large auxiliary water consumption, and 10m of wastewater to be discharged and treated. 3 More than / ton of dry starch, the cost of sewage treatment is high, the steam consumption is serious, and it is easy to cause environmental pollution. (3) Contents of the invention [0003] The technical task of the present invention is to address the deficiencies of the prior art and provide a starch that can effectively reduce the auxiliary water used in the production process of corn starch, save the cost of sewage treatment, increase the dry matter yield of starch and by-products, and reduce the impact of the produc...
