Method and apparatus for uniformly spraying liquid onto materials

Abstract

The invented method utilizes a conveying appliance to throw-feed the spreact-thinned material into a charging machine, then uses a nozzle placed in the charging machine to spray the liquid material on the layer-like throw-fed material. Said invented equipment includes conveying machine, charging cabinet, material-falling cabinet, material channel, sensor and liquid material nozzle, etc.

Description

technical field [0001] The invention belongs to the technical field of methods for uniformly spraying material liquid on the surface of materials, especially for the methods used in food, tobacco, medicine and other industries to process materials such as flavoring, feeding, and enzyme addition. The invention also provides a method for this method. installation. Background technique [0002] The process of flavoring and adding ingredients plays a very important role in the production process of food, tobacco and pharmaceutical industries. For example, in the cigarette process, the aroma and taste of cigarettes mainly depend on the type and quality of tobacco leaves. As tobacco is affected by natural conditions and cultivation conditions during the growth process, the quality of raw materials will inevitably change, resulting in changes in the aroma and taste of cigarettes. Although technical applications such as tobacco and tobacco sheets have greatly reduced the amount of...

Problems solved by technology

The device used in this feeding and flavoring method is called a feeder or a flavoring machine in the industry. Its outstanding feature is that the transportation of materials and the processing of feeding and flavoring are completed simultaneously in the rotating drum, but there are several disadvantages: 1. It is the uneven spraying of the material liquid. One of the reasons is that the thickness of the material layer formed when the material is picked up by the copying plate in the drum and then falls is relatively thick, and the atomized material liquid sprayed out by the nozzle is only sprayed on the surface of the surface material; the second is The number of nozzles is limited. For example, there is only one nozzle in the aroma adding machine. The feeding machine is usually equipped with 1 to 3 nozzles according to the feeding ratio, and usually all of them are installed at the feeding end or the discharging end of the drum, so it is difficult to guarantee The uniformity of spraying liquid on the material

Second, because the nozzle is far away from the material layer, about 1m, part of the atomized material liquid is easily taken away by the circulating hot air or tidal wind flowing along the axial direction of the drum, which not only causes the loss of the material liquid, but also causes the loss of this part of the material liquid. Pollution of air ducts, fans and filters, etc., will adversely affect the operation of equipment

These two disadvantages have caused the instability of the quality of cigarette products, and because there is no good way to actually apply it in the cigarette production process at present, it only depends on storing in the storage cabinet for a period of time to balance the uniformity of the material liquid through the accumulation of materials. , can not fundamentally solve the problem

In addition, the material is constantly tumbling in the drum, which increases the crushing and reduces the quality of the material
