Description

Roller spraying machine

Technical Field

The utility model relates to a flush coater in food industry or fodder trade.

Background

The purpose of using coating machines in the food and feed industries is to allow liquid fat or liquid fat containing powders to be uniformly coated on the surface of the pellets and absorbed into the interior of the pellets.

The spraying environment is distinguished from the pressure of the spraying environment, and the spraying can be divided into two modes, namely normal-pressure spraying and vacuum spraying. The normal pressure oil is sprayed on the surface of the particles, and less oil is absorbed into the particles. Vacuum spraying, where the grease is sprayed on the surface of the particles, will allow more grease to be absorbed into the interior of the particles. Both of these approaches are used in many situations.

The existing normal pressure spraying and vacuum spraying have many problems.

Constant pressure continuous roller spray is a common spray application device. The biggest problem of such spray coating is that the amount of grease added is not accurate. Many plants produce a annual statistical oil inventory with tens of tons of oil being depleted or tens of tons of oil being enriched. The price of these tens of tons of grease is considerably more expensive than that of the roller painting equipment. This has led to more users being reluctant to eliminate atmospheric roller spray.

Vertical batch applicators are another common type of spray application equipment. The spraying equipment can be normal pressure spraying or vacuum spraying. This flush coater has solved the inaccurate problem of grease interpolation because let material and grease all weigh. But the vertical spraying machine uses the vertical spiral auger to drive particles to circulate in the spraying machine so as to achieve the purpose of uniform spraying. The biggest problem with this solution is severe fragmentation.

Horizontal batch applicators are a third type of conventional spray equipment. The spraying equipment can be normal pressure spraying or vacuum spraying. This flush coater has solved the inaccurate problem of grease interpolation because let material and grease all weigh. But the horizontal spraying machine drives the particles to turn over in the spraying machine by using the blade rotor so as to achieve the aim of uniform spraying. The biggest problem with this solution is also the problem of breakage, often the horizontal batch applicators break more severely.
