Aseptic Sterilizer

GOMA provides a UHT Plant for the sterilization of low-acid foods, Ultra Heat Treatment (UHT) process involves heating over 135 °C. to destroy all microorganisms and enzymes. This is done to increase the shelf life of the end product to such an extent that it can remain imperishable for more than 6 months, making the product suitable for ambient distribution.

We manufacture UHT plants for Milk, Flavoured Milk, Yoghurt, Lassi, Mahew drinks, Coconut water, Coconut Milk and Coconut cream, Fruit Juices, fruit pulp, etc. We provide a solution for smaller capacity (Lab/ R & D Model) to commercial production of 10,000 LPH.

GOMA UHT Model is designed to incorporate the proven features and performance of models currently in the Skid mounted aseptic UHT Sterilizer along with energy efficiency & and improved product quality.

There are two methods used to produce these sustainable products

In-container sterilization method

In this method, the packaged product is sterilized after the container has been filled and hermetically sealed. Hence, the product is sterilized using the UHT sterilizer inside the container. This method offers the benefit of single-stage sterilization and eliminates the need for aseptic packaging.

Ultra Heat Treatment method

In this, the food is sterilized by heating it above 135 °C (275 °F). The final product will be packed under sterile conditions using sterilized containers like Aseptic bricks, Aseptic BIB, Aseptic pouches, etc.

GOMA UHT includes a regenerative type preheating section, a heating section and cooling section, and hot water-based heating section, a stericooler& all other accessories,

The sterilization process will be with online homogenization at 250 bar, also the provisioned with options of online/offline DE aeration system. 

This heating method of UHT processing is further categorized into two types i.e. The Direct heating system and the indirect heating system.

Direct heating system –

In this system, the product is directly exposed to the culinary steam, flush cooling in a vacuum vessel, which is then followed by cooling & aseptic filling

Indirect heating system –

The direct system may be plate heat exchanger based; tubular heat exchanger based or scraped surface heat exchanger based. The direct Ultra Heat Treatment processing prioritizes the chilling of liquid food.

Nowadays the indirect heating system is enormously popular and widely used exclusively for liquid foods to achieve very high product quality.

With indirect UHT processing, chilled liquid food is firstly preheated, homogenized (180-250 Bar), and exposed at 135-140 degrees Celsius for 2-4 seconds to confirm the destruction of microorganisms followed by cooling & aseptic filling in BIB, pouches, or bricks.
