Production technology of ellipsoidal suckling pig milk replacer

Abstract

The invention relates to a production technology of an ellipsoidal suckling pig milk replacer, and belongs to the technical field of processing of feeds. The production technology comprises the specific technological steps of elevating milk replacer powder into a bin, and uniformly transporting the powder into a counter roll granulating machine through a quantitative material feeder; performing extrusion to obtain sliced semi-finished products formed by uniform arrayment of ellipsoidal granules, enabling the semi-finished products to enter an edge damage machine, performing edge damage, after edge damage, performing sieving and classification, enabling granules or powder, which does not conform to the specifications to return to a system, performing granulation or edge damage once again, determining the ellipsoidal granules which conform to the specifications as finished products, packaging the finished products with a packaging system, performing warehousing, and performing storage. The milk replacer produced by the method disclosed by the invention can be directly fed to suckling pigs, the defect that a conventional powered milk substitute needs be added with water to be fed to the suckling pigs is overcome, the waste of feeds is reduced, the raising efficiency of pigs is improved, the labor intensity of raising staff in a piggery is greatly reduced, and the purpose that the suckling pig eats the milk replacer in a dry feeding manner is successfully realized.

Description

technical field [0001] The invention belongs to the technical field of feed processing, and in particular relates to a production process of an ellipsoid suckling pig milk substitute. Background technique [0002] my country's pig herd accounts for half of the world's total, with about 700 million pigs slaughtered annually. According to statistics from the Ministry of Agriculture, domestic pig feed production in 2015 was 83.44 million tons. From the point of view of feed type, most of them are compound feed, a considerable amount of premixed feed and a small part of concentrated feed; from the perspective of use stage, the feed for medium and large pigs and sows account for about 90%, and the feed for suckling pigs accounts for about 10%. . At present, all the compound feeds that are compressed into cylindrical shapes must be completed through a conventional feed pelleting system. The general process is that the uniformly mixed powdered feed is steamed at 60-90°C, and then...

AI Technical Summary

Problems solved by technology

Milk replacer for sucking pigs cannot be made into cylindrical granules through the conventional feed pelleting system because it contains high levels of heat-sensitive raw materials such as dairy products, sugar, and milk protein. The main reasons are: 1. High-level dairy products will It will become mushy and stick to the modulator, causing the modulator to fail to work normally; and when granulating after modulation, it will stick to block the granulator, which will also cause it to fail to work normally; 2. High levels of sugar after granulation will cause The hardness of the granules increases, and the palatability decreases; 3. The heat-sensitive raw materials will deteriorate at the moment of high-temperature modulation and granulation, resulting in a decrease in their nutrient utilization

Therefore, many suckling pig milk replacers are made into powdered feed, but powdered suckling pig milk replacer has the following three disadvantages: 1. From the perspective of feed utilization efficiency, the utilization efficiency of powder is lower than that of compressed granulated feed, Because the feed waste rate of powder is higher than that of pellets; 2. The incidence of respiratory diseases in piglets fed with powder is higher than that of pellets, and the fine particles in powder can easily enter the respiratory system of pigs, leading to respiratory inflammation; 3. Some Milk replacer for suckling pigs containing high levels of dairy products cannot be directly fed to suckling pigs (dust enters the respiratory tract and is very viscous, sticks to the mouth when it meets water, and pollutes the pen), and must be mixed with water to form a "soup" before feeding , and the modern pig feeding soup has a lot of work in terms of mixing water and materials, cleaning pens, cleaning troughs, etc., so "soup" is difficult to promote
