The extensive definition of food industry is that all processes in which agricultural and animal materials can be become edible. Food industry consists of hundreds of treatment lying from clening to processing, from preserving to packaging and thousands of natural products which are from salt to sugar, from wheat to flour.
From raw material to edible food, the food processing has several steps as follows:
Cleaning: Washing, peeling, removal of foreign materials, cleaning in place (cip).
As you can see the above list, food processing has included a lot of stages. Let’s look at usages of roots blowers in food industry.
Roots blowers have an indispensable position in food industry as well as in many industries. Thanks to their oil-free operation, the roots blower pumps supply the clean air that is a very significant element especially in food processing.

How to use roots blowers in food industry?
Roots Blowers for Pneumatic Transport:
Roots blowers are used to convey granular and powder materials in food industry. Please click here for more information that how to use roots superchargers in pneumatic transport.
Roots Blowers for Confectionery Industry:
The roots blowers are Roots Blowers for Enrobing and Enrobers utilized at enrobing process in the confectionery industry. Enrobing is a covering operation that candies and snacks are coated with molten chocolate in confectionary industry. Enrobing makes better the taste or appearance of candies and also prevents absorption of moisture in the center. Enrobing is done by machines called as enrobers. Centres pass through the enrober and flows towards a continuous coating curtain. The centres are covered with chocolate during passing under the coating curtain. After this stage, overflow chocolate on the product is forced off by means of a positive displacement roots blower. In other words, roots blower pumps are employed to skim by air flow the excess chocolate that staying on the products. Both better looking candies and regiving the surplus chocolate to the system have been acquired by means of a blower.
Roots Blowers for Thermal Processing:
In the food industry or called food processing industry, the thermal processing is using of high temperatures in order to get long-term preservation of foods against harmful effects of microbial destruction. Thermal processing is also determined as Critical Control Point –CCP.
There are two categories of thermal processing:
1. Pasteurization: Processes that are implemented between 70 -100°C.
2. Sterilization: Processes that are implemented over 100°C.
Heating is made by using mixture of air and steam within a retort for thermal processing. The positive displacement roots blowers are employed within the retort in order to produce sufficient flow to get steady temperature and steady velocity.
Roots Blowers for Mechanical Vapor Recompression (MVR):
MVR, Mechanical Vapor Recompression, is a recycling system that generates energy by recovering waste heat. Mechanical vapor recompression is utilized in many industrial applications as much as in food industry like saline, dairy, distillery etc. Roots type blowers are made use of to handle large volumes of vapor in these systems.
Roots Blowers for Cabinet Dryers:
Cabinet dryers, are industrial systems that are employed for drying the foods which are in enclosed place on trays or products holders by means of heated air. Cabinet dryers are widespread systems that are used in food industry applications for food dehydration. Food dehydration is a process for decreasing food moisture to extend shelf life of food. Some cabinet dryers operate with vacuumized air. rotary air blowers are utilized to provide vacuumized air to cabinet dryers.
