Vertical vacuum sprayer

Unique Technology and Design of the Zhengchang Vertical Vacuum Coater

The vertical vacuum coater is mostly used to coat and flavour pelleted feed. It improves the taste of the feed and so increases feed intake by aquatic animals. This is especially important in aquaculture, where the taste and texture of feed influence the feeding behaviour of aquatic animals.

In addition to improving taste, nutrients and supplements are sprayed onto the surface of the pellets. For example, essential vitamins, minerals or supplements are added to feed produced by pellet mills or extruders to ensure aquatic animals receive a complete diet. The vertical vacuum coater ensures these nutrients are evenly distributed and improves feed quality.

The vertical vacuum coater is 4.5 m high and 2.2 m wide, weighs 4.8 tons, has a volume of 2,000 litres and can process 800 kg of material per batch.

The machine’s three-leg structure is stable, finished in black and grey, with a stainless steel, sand-blasted surface. Components from top brands are used in the vacuum and sealing systems. Good sealing gives a high-quality vacuum system and a longer service life. Overall, the vertical vacuum coater is stable and reliable and can meet customer needs for multiple formulations.

The nozzle and pipe are designed for fast discharge and are easy to clean and maintain. The discharge gate design is patented and unique. The machine can be fitted with a hot-air system to prevent bacterial growth and meet customers’ hygiene requirements. It can also protect certain sensitive ingredients in the raw materials and help customers achieve the best product quality.
