Greencold offers Blast Freezer & Chiller systems to the food processing industry.

Blast Chillers

Blast chilling is a method of cooling food quickly to a low temperature that is relatively safe from bacterial growth. Bacteria multiply fastest between +8 °C (46 °F) and +68 °C (154 °F). By reducing the temperature of cooked food from +70 °C (158 °F) to +3 °C (37 °F) or below within 90 minutes, the food is rendered safe for storage and later consumption. This method of preserving food is commonly used in food catering and recently, in the preparation of 'instant' foods as it ensures the safety and quality of the food product.

Blast Freezer 

blast freezer is just a freezer which is extremely cold. They can sometimes be referred to as ‘shock freezers’ too. The concept behind shock freezers is to quickly reduce the temperature of food products or fresh produce in order to reduce the metabolic processes significantly. They are often used in the food industry for products such as ready meals, chicken,meat,fish and vegetable products. Many commercial kitchens use blast freezers for cold storage

blast freezers use blower fans which emit cold air across the contents of the freezer which causes rapid chilling. Others can work in different ways depending on the design. They can be equipped with trays or pallets that are adjustable, allowing users to position foods into various compartments for freezing.

When food is frozen, the water inside it crystallizes. If freezing takes place at relatively warm temperatures, the ice crystals which form will be large. In a blast freezer, the extremely cold temperature promotes very rapid freezing, which creates small ice crystals. The smaller the crystals, the less damage to the food, as large crystals can rupture cells. Once the food has been frozen in a blast freezer, it can be moved to a more conventional freezer for storage, as long as the freezer stays cold enough to keep the food frozen.

Energy saving, defrost as well as noise reduction mode of the freezer make Greencold highly popular in the market. Apart from the obvious advantages such as a higher quality, better tasting product, our blast freezing also offers health and safety benefits. The extreme temperature dramatically slows down metabolic activity. Moreover, it locks the taste, color, texture, flavor, as well as nutritional value of the food quickly.
