Method for adding enzymic prepns. by electrostatic spraying

Abstract

An electrostatic spray method for adding enzyme preparation to feed features that a negative-voltage electrostatic generator is used to negatively charge granular feed, and the solution of enzyme preparation is spray through an electrostatic inducing ring to positively charge it and then onto said negatively charged granular feed.

Description

technical field [0001] The patent of the invention relates to the technical field of feed processing in agricultural engineering, in particular to an enzyme preparation electrostatic spraying method for adding enzyme preparation to feed. Background technique [0002] In the feed industry, although the additive industry started late, it is growing at a high speed. The traditional enzyme preparation process uses solid enzyme preparations to be mixed and added to the compound feed. At this time, the enzyme preparation additives have to withstand the harsh environment of high temperature, high pressure and even high humidity, and it is easy to lose a large amount of enzyme activity, resulting in enzyme preparations. a great waste. Later, it developed to adopt the liquid addition process. In this respect, certain researches have also been carried out at home and abroad, such as the use of vacuum liquid addition process, direct addition of suspension or colloid process, post-plac...

AI Technical Summary

Problems solved by technology

However, the vacuum liquid addition is mainly for the addition of oil, and there are not many applications for the addition of enzyme preparations.

Direct addition of suspension or colloid process has the disadvantage of poor addition uniformity

The post-placed ordinary atomized enzyme preparation liquid addition process (such as pressure spray, centrifugal spray, etc.) has a large average spray droplet diameter, poor feed droplet size uniformity, poor deposition effect, and cannot achieve the desired enzyme Uniformity requirements for formulation spraying
