Problems solved by technology

[0004] There are also local people who ferment cassava residues with additives and then use them to raise pigs. Because cassava residues contain too much crude fiber, they cannot be used in large quantities for pig raising. Moreover, these fermented cassava residues cannot be stored for too long. They must be stored in a few days. The internal feeding is completed, so the cassava dregs still cannot be solved

Embodiment Construction

[0033] 1. Operation steps:

[0034] (1) Under the agitation of the cassava slurry in the slag pool, use the hydraulic plunger pump to extract the slurry and press it into the plate and frame filter press to squeeze out the water. When the pressure of the filter press rises to 1.0-1.2KPa, keep Press for 1 hour to unload.

[0035] (2) The unloaded filter cake is crushed by a crusher within a particle size of 5mm, and then the crushed material is weighed, and the thickness of the spread is about 8cm.

[0036] (3) Weigh 0.1 kg of dimethyl fumarate according to 100 kg of slag material, put the dimethyl fumarate into a duster, and open the duster to evenly spray on the slag material.

[0037] (4) Put the above-mentioned slag into the mixer and stir evenly, and then pack the finished product through a packaging machine.

[0038] 2. Comparison of economic benefits

[0039] Take the plate and frame filter press to filter cassava dregs with a water content of 35% as an example: the s...

Abstract

The invention discloses a cassava residue mildew preventing and freshness keeping method. The method comprises the following steps: pumping a cassava residue slurry to a plate and frame filter press by using an oil pressure plunger slurry pump, dehydrating to about 35%, crushing the obtained unloaded filter cake by a crusher, adding dimethyl fumarate to the above obtained residues, uniformly stirring, and packaging to form a finished product. The method makes the mildew preventing and freshness keeping period of cassava residues reach above 3 months, and basically meets the transportation and storage needs of feeding households.

Description

technical field [0001] The invention relates to a method for anti-mold and fresh-keeping of cassava dregs, which is to add dimethyl fumarate during the processing of cassava dregs to achieve the purpose of anti-mold and fresh-keeping. Background technique [0002] Guangxi is a large province producing cassava starch. It produces about 300,000 tons of starch every year during the cropping season, and about 900,000 tons of cassava dregs are produced by it. The cassava dregs are stored in the dregs pool at the end of the cropping season. The main components of cassava dregs are crude fiber and a small amount of starch, which can be used as feed supplements. Pig farmers around the starch factory often go to the factory to get some cassava dregs to feed pigs. However, pigs need more concentrated feed. Cassava The slag is useless as roughage, which is why local feed factories cannot use cassava slag as raw material. Therefore, these small quantities of demand are far from solving...
