Device is fed, which is attached to the outside of the discharge opening and the product in a Collector, trough or drops onto a transport device.

In addition to coating products with powdery This invention is also intended to prevent substances such as sugar, starch, etc. from scattering powder inside the container will.

The invention consists in a specially designed to distribute the

Product batch designed device.

The powder material is supplied with air as a transport medium and when it comes into contact with the product during the coating process absorbed by this, with the introduced air being filtered at the same time.

The advantage of this system is that powder remaining inside the container and contamination of the Prevents production rooms and at the same time ensures that all articles are uniform during the coating phase Distribution of the powder is achieved.

It is known that today a large part of the products candied or coated in devices of this type by application be flavored by flavoring substances in liquid or powder form.

As for the flavoring agents in powder form, these are in the present device by the use of those previously described Device for the distribution of powder inside the container and distributed under the product.

This invention is intended to suitably serve to distribute the liquid flavoring agents necessary to achieve to give the product a certain taste.

The process used so far is entirely manual, the aromatization of the product is therefore to a high degree by depending on the skills of the worker. The aim of this invention is the distribution of liquid or powder Automate flavoring substances under the product in a simple and safe way and because of the low Loss of aroma that the device allows savings to be achieved.

With the system that is the subject of this invention, the flavoring agents are metered throughout the coating cycle distributed under the product. In this way there is a constant quality of the products and a perfect distribution of the flavoring substances reached over the entire coating layer.

At the same time, this system enables complete absorption of the dosed flavoring substance before it evaporates can.

All of the features described so far, as well as other features, are illustrated with the diagrams of the invention in the accompanying drawings Illustrated in pictures.

In these drawings is the base or pedestal on which the whole device is at rest, marked with "A". All the devices for the automatic are also located here Drive the device (motor, gearbox, fan, battery for cold or hot air supply, pumps for the products, etc.). As can be seen from Figures 1 and 2, the device is very compact and has the advantage that no dust in the room can escape and air can still be sucked in from the outside. It is also for the use of air filtration equipment designed so that the air can be supplied without bacteria.

The rotatable container "B" (pictures 1, 2 and 3) consists of three parts marked 1, 1a and 1b made of stainless steel or other materials. The two lateral cup-shaped parts are welded to the central part 1, so that the Container has the shape of an onion or something similar.

In the container "B" are the deflection devices 2, which are designed both in terms of their shape and their dimensions in such a way that the cups 1a and 1b (Figs 1 and 2) can automatically mix the product while the container is rotating.

The cup 1a (pictures 1 and 2) is provided with a concentric opening on the axis of rotation "X", which is used for automatic Loading and unloading of the product. A lid is attached over this opening.

This lid has a mechanism through which it can be brought into two different positions. In the first position, by separating the cover from the Mixing drum the loading and unloading process are carried out,

• 9 ·

the cover for switching from loading to unloading function or vice versa only has to be rotated by 180 °. In the other position, the lid adheres firmly the drum and thus rotates with it during the enrobing processes.

The lid 3 is designed in terms of shape and dimensions so that it also serves as a loading funnel, the Product collects while the container rotates in the opposite direction and the deflectors 2 the finished product Product / continuously discharged after it has the has reached a critical fall angle.

The product collected in this way is led to the exit of the lid and then arrives at an unloading tube which is carried out in this way is that the fall of the product is braked and this at a reduced speed in the Collection tray falls.

A flange with reinforcements 4 is mounted on the cup 1b as part of the same and with the suitable rotary drive coupled, which transmitted its movement directly from a motor 15 with adjustable reduction gear receives.

The cup 1b has a drive and an axis of rotation "X" concentric opening with press ring 5, through which the used and previously into the mixing drum through 7 (coaxial to the said cylindrical press ring) introduced air is sucked out.
