Problems solved by technology

Powdered feed with too low moisture content generally has two problems. One is that powdered feed with too low moisture content, especially the variety with high crude fiber content, will bring difficulties to the subsequent pelleting process, and ring die often occurs. Blockage or coking of pelleted feed makes it impossible to produce; second, powdered feed with too low moisture content is prone to dust flying, polluting the environment and endangering the health of workers

Embodiment 1

[0015] Known conditions: the winter temperature in the north is 1°C-8°C, the production of No. 1 powder concentrate, the moisture content of the powder feed is measured at 10.2%, the required moisture content is 13%, and the production capacity of each batch of mixer is 1 ton.

[0016] Then the amount of water added in this batch is: 1000×(13%-10.2%)=28(kg)

[0017] Choose 3% corn oil for the amount of fuel, that is, 1000×3%=30(kg)

[0018] The emulsifier is 0.5% polyglycerol polyricinoleic acid ester, and the dosage per batch is 30000×0.5%=130(g)

[0019] Considering the low temperature in winter and the dry climate in the north, antifungal agents and antioxidants are no longer added, so the emulsion is composed of 28kg of water, 30kg of oil, and 130g of polyglyceryl polyricinoleate. After being homogenized in a homogenizer, a uniform emulsion is obtained, which is stored in an intermediate tank, sprayed into a mixer by a quantitative jetting machine, and fully mixed with 1 ...

Embodiment 2

[0022] Known conditions: In the rainy spring season in the south, the temperature is 18°C-24°C, and the No. 2 powder concentrate is produced. The moisture content of the powder feed is measured at 10.85%, and the required moisture content is 13%. The production capacity of each batch of mixer is 2 tons. .

[0023] Then the amount of water added is 2000×(13%-10.85%)=43(kg)

[0024] Choose 3% vegetable oil for the amount of fuel, that is, 2000×3%=60(kg)

[0025] The emulsifying agent that adds, selects the sucrose fatty acid ester of 0.25% for use namely 60000 * 0.25%=150 (g)

[0026] The antifungal agent added is 0.1% propionic acid because it is suitable for mold growth in the mildew season: that is, 2000000×0.1%=2000(g)

[0027] Since the temperature is lower than 30°C, no antioxidant is added to the emulsion.

[0028] Therefore this batch of emulsion is made up of: water 43kg, oil 60kg, sucrose fatty acid ester 150g, propionic acid 2000g, sprays in the mixer with the same...

Embodiment 3

[0031] Known conditions: the summer temperature is 31°C-37°C, the production of No. 3 powdered feed, the final product is required to be granular, and the raw material of this batch of feed contains high crude fiber (the amount of rapeseed meal and wheat bran is large) which is not conducive to pelleting. The moisture content of the feed is measured to be 10.60%, and the desired moisture content is 13%. The production capacity of each batch of the mixer is 1 ton.

[0032] Then the amount of water added is 1000×(13%-10.60%)=24(kg)

[0033] Choose 1% soybean oil for the amount of oil, that is, 1000×1%=10(kg)

[0034] Add the amount of emulsifier to choose 0.25% monoglyceride, that is, 10000×0.25%=25 (g)

[0035] When the temperature is high, an antioxidant should be added to choose 0.1% tea polyphenols, that is, 10000×0.1%=10(g)

[0036] Since it is a high temperature season, which is not conducive to the growth of mold, this batch may not be added with antifungal agent. Ther...

Abstract

The method of regulating water content in powdered feed includes compounding mixed emulsion with oil, water, emulsifier, mildewproof agent and antioxidant in calculated water ratio, homogenizing in a homogenizer to form water-in-oil emulsion, and spraying the emulsion in a mixer for mixing with the powdered mixed feed to reach the required water content. The said process can reduce flying dust, improve work condition and raise feed producing efficiency.

Description

technical field [0001] The invention relates to a method for adjusting the water content of feed, more specifically, the invention relates to a method for adjusting the water content of powdered feed. Background technique [0002] According to the appearance of the feed, it can be divided into granular feed and powder feed. The moisture content of the powdered feed is determined by the moisture content of the raw material itself and the proportion of the raw material in the formula. In production practice, due to the raw material itself, the moisture content of powdered feed produced in many cases is low, which is generally lower than the national standard. Powdered feed with too low moisture content generally has two problems. One is that powdered feed with too low moisture content, especially those with high crude fiber content, will bring difficulties to the subsequent pelleting process, and ring die often occurs. Blockage or coking of granular f...
