Our product is a result of several years of Research & Development assisted by feedbacks received from prevailing technologies at farmer & milling locations & in depth understanding of grains through reputed Agriculture Universities. Our Primary focus remains to build technology products that are cost effective, sustainable and highly reliable for Preservation of grain. Our primary focus was to assess the root cause of the nation’s stored crop wastage and the best suitable method to preserve grain without losing its nutritional properties. Our core product, the Grain Cooler utilizes the latest technology in the field of refrigeration to control temperature & humidity levels of the grain, stored in either silos or warehouses. By achieving the desired temperature & moisture levels, the grain can be kept safe from any insects, fungus or any losses associated with drying. The GT-Series Grain Coolers are custom built as per environmental conditions & customer requirements. Using the most up to date techniques such as VFD Driven Motors & Compressor Discharge Recycle, we ensure that our product is not only more efficient in operation but keeps running costs to a minimum.

A GT Grain Cooler is controlling both temperature and the relative humidity of the cooled air – regardless of ambient conditions – no need for using highly toxic chemicals to protect grain in storage from being damaged by insects.

The ‘GT-CLOUD’ Temperature Monitoring System can also prove to be very advantageous to our customers. The system is designed for heavy duty, highly reliable and daily remote monitoring use. Using automated live feeds to show the grain temperature & capacity, the user can adjust Cooling set points remotely to ensure efficient Cooling of stored grains.

Do not let your hard earned harvest go to waste. Learn why Preservation of grain through Cooling is a must!

Cooling in a silo

The cooled air is distributed in the silo/flat storage through a duct system in the bottom of the silo/flat storage. As the cooled/conditioned air moves up through the grain mass the temperature in the grain is reduced, eventually reaching the set value. Grain being an excellent insulator, once cooled to a low temperature, will remain cool for a substantial time period.

A food grain, apart from being our most essential staple requirement, is also a high contributing factor to any nation’s wealth. It is farmed and harvested with great care and effort. According to the World Food Organisaton, 1.3 billion tons of grains are wasted every year globally. The major causes of wastage are due to insects, fungus and drying. Grain is also a living organism, which means that when it breathes, it releases carbon dioxide, water and heat. This process leads to loss of weight and quality. The natural heat generation depends on various factors, one of them being the moisture level and temperature at which it is stored. A typical storage condition in a humid & tropical country with ambient temperatures in the range of 30-35 Deg C & Grain moisture content of 15% would lead to heat generation of about 1MJ/T per day, continuously increasing every day.

In addition to grain respiration, insect infestation is also a consequence of natural heat generation. The grain infesting insects being very temperature sensitive, multiply rapidly in temperature zones between 23 Deg C to 33 Deg C. Temperature conditions of 15 Deg C & below are ideal to prevent breeding of most insect species. Even more so, 13 Deg C & below keeps the insects in hibernation without any activity.

Fungus development is another factor contributing to wastage of grains & is also mostly influenced by temperature, humidity and grain moisture content. When warm air from the centre of a bulk/ bin meets cold grain at the surface, condensation may occur. Moisture at the surface or in damp pockets in the bulk will encourage moulds and sprouting. These are toxic for human and animal consumption. Mycotoxin formation is also most likely between temperatures of 16
Deg C and 25 Deg C. By controlled humidity and temperature conditions, the risk of insects and fungus infestation is eliminated.
