Embodiment 1

[0031] For the production line of 600 tons / day wet processing corn starch, add the above compound enzyme preparation, the initial addition amount is 0.1‰, and the addition amount is adjusted to 0.03‰ after 24 hours. The adding point of the enzyme preparation is the middle tank of fiber washing, and the feeding is continued for 30 days. In the production process of wet processing corn starch, the transportation of raw materials depends on the transportation of process water. In addition to fresh water for starch washing, other water such as germ washing and fiber washing is process water, and the process water can be recycled.

[0032] Table 1 Comparison of relevant data for 30 days of continuous production

[0033]

[0034] Benefit Analysis:

[0035] Starch yield increased by 1.0%, that is, more starch produced = 600 tons / day × 1.0% = 6 tons / day;

[0036] Corn starch is calculated at 3,000 yuan / ton, and direct economic benefits = 6 tons / day × 3,000 yuan / ton = 18,000 yua...

Embodiment 2

[0042]For the production line of 600 tons / day wet processing corn starch, add the above compound enzyme preparation, the initial addition amount is 0.15‰, and the addition amount is adjusted to 0.08‰ after 24 hours. The adding point of the enzyme preparation is the middle tank of fiber washing, and the feeding is continued for 7 days.

Embodiment 3

[0046] For the production line of 300 tons / day wet processing corn starch, add the above compound enzyme preparation, the initial addition amount is 0.15‰, and the addition amount is adjusted to 0.06‰ after 24 hours. The adding point of the enzyme preparation is the middle tank of fiber washing, and the feeding is continued for 7 days.

Abstract

The invention discloses a method for improving starch yield in a corn starch processing process by using a complex enzyme preparation, which is characterized in that the complex enzyme preparation is cellulose, xylanase, pectinase, beta-dextranase, a stabilizer sodium chloride and a carrier corn starch. In the processing process for producing the corn starch by taking the corn as a raw material, the complex enzyme preparation is added to the fiber washing procedure. The yield of the starch is improved by the procedures of washing and drying the fiber, separating and drying corn protein, soaking and crushing corn, and separating and washing corn germs; and the adding amount of the complex enzyme preparation is 0.01-0.15 per mill of the weight of the corn. According to the method disclosed by the invention, on the basis of a traditional wet processing process, the enzyme preparation is added in the corn separating process, so that the mechanical separating efficiency is improved, and thus the yield of the corn starch and corn protein powder is effectively improved; and meanwhile, energy consumption can be effectively reduced.

Description

technical field [0001] The invention belongs to the field of enzyme preparations, and in particular relates to the production of a composite enzyme preparation and its application in the starch production process. Background technique [0002] Corn is a high-yield food crop and one of the main crops in my country. Corn starch is the main basic raw material for deep processing of corn and is widely used in various industries. At present, domestic corn starch processing generally adopts wet processing technology, mainly using mechanical methods such as soaking, crushing, screening, centrifugation, extrusion, and filtration to separate, concentrate, and dry starch, protein, germ, and fiber in corn. In this process, there is still a small amount of starch not separated in the steps of germ separation, fiber washing, protein separation, etc., which has the problems of low yield of corn starch, high production cost and high energy consumption. [0003] The compound enzyme prepara...
