Multifunctional trace-element spraying unit

Abstract

The invention relates to a multifunctional trace-element spraying unit which comprises a water heater. The water heater is connected with a water outlet pipe through a group of hot water pipeline pumps, the water outlet pipe is connected with a trace-element burdening tank I and a trace-element burdening tank II respectively, the trace-element burdening tank I is connected with an electromagnetic diaphragm pump I through a discharging pipeline, and the electromagnetic diaphragm pump I is connected with a trace-element spray head I through a spraying pipeline I. The trace-element burdening tank II is connected with an electromagnetic diaphragm pump II through a discharging pipeline II, the electromagnetic diaphragm pump II is connected with the trace-element spray head II through a spraying pipeline II, and the trace-element spray head I and the trace-element spray head II are also respectively connected with an air heater. The multifunctional trace-element spraying unit performs heating through the water heater and burdening in two groups or multiple groups of trace-element burdening tanks, multiple groups of trace-element burdening tanks can work in a simultaneous, independent or one-group mode, other parts assist preheating, the spraying work is automatic and is also divided in a stepped mode, and the spraying efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of spraying equipment, in particular to a multifunctional trace element spraying unit. Background technique [0002] There is a layer of free fat on the surface of whole milk powder with strong water repellency. In order to make it instant, the particle surface must be treated with a surfactant; trace elements are inherent components in milk and have strong hydrophilicity, which is ideal for instant milk powder. Active agent; trace elements must be diluted into a solution with anhydrous good cream before spraying, this solution is called a wetting agent below; the amount of trace elements sprayed varies with the amount of free fat in the powder, particle structure and agglomeration, The powder to be treated is 0.1-0.4%, usually not less than 0.2%, and the total amount of free fat after spraying (sprayed trace elements and anhydrous cream - the original free fat) is generally 1-2%; The ratio of the agent is:...

AI Technical Summary

Problems solved by technology

[0003] The current degree of automation of spraying equipment is insufficient, and often requires manual participation in the spraying process, which not only increases manpower and physics, but also cannot ensure that the spraying temperature and spraying speed meet the spraying requirements of whole milk powder.
