Description

A roller sprayer

technical field

The invention relates to a spraying machine in the food industry or the feed industry.

Background technique

The purpose of using sprayers in the food industry and feed industry is to spray liquid grease or liquid grease containing powder evenly on the surface of the particles and absorb them into the interior of the particles.

From the pressure of the spraying environment, it can be divided into two ways, one is atmospheric spraying, and the other is vacuum spraying. Atmospheric pressure spray grease is sprayed on the surface of the particles, and less grease is absorbed into the particles. In vacuum spraying, grease is sprayed on the surface of the particles, and more grease will be absorbed into the particles. These two methods are used in many situations.

There are many problems in the existing atmospheric spraying and vacuum spraying.

Atmospheric pressure continuous drum spraying is a common spraying equipment. The biggest problem with this type of spray is that the amount of grease added is inaccurate. When many factories produce oil inventory for one year, they will find that dozens of tons of oil are missing or dozens of tons more oil. And the price of these dozens of tons of grease is much more expensive than the price of roller spraying equipment. This has led to more users who are determined to eliminate atmospheric pressure roller spraying.

Vertical batch sprayers are another common type of spraying equipment. This type of spraying equipment can be atmospheric spraying or vacuum spraying. The sprayer solves the problem of inaccurate addition of grease because both materials and grease are weighed. However, since the vertical spraying machine uses the vertical screw auger to drive the particles to circulate in the spraying machine, in order to achieve the purpose of uniform spraying. The biggest problem with this scheme is that it is severely broken.

Horizontal batch sprayers are the third most common spraying equipment. This type of spraying equipment can be atmospheric spraying or vacuum spraying. The sprayer solves the problem of inaccurate addition of grease because both materials and grease are weighed. However, because the horizontal sprayer uses the paddle rotor to drive the particles to turn over in the sprayer, in order to achieve the purpose of uniform spraying. The biggest problem of this scheme is also the problem of crushing, and the crushing of horizontal batch sprayers is often more serious.
