19. MOISTURE PROBLEM APPLICATION OF DEHUMIDIFIER IN FOOD INDUSTRY

20. Indian Food Industry : Moisture problem confectionery products ,such as Chocolates, hard candies, chewing gums , are hygroscopic . In high humidity these products regain moisture and prone to mould formation. This inhibits the natural flow (sticks to the high speed processing and packaging machinery and the wrapping material) The processing thus slows down, creates a problem of hygiene, loss of production as well as loss in the final product quality.

21. Moisture Problem Uncontrolled humidity/moisture during the manufacturing and coating process of confectionery causes: ● Change in the structure/dimension of interface ● Grainy and irregular coating ● Increase in residual moisture content adhesion i.e. degradation of coating quality in the presence of moisture ● Sugar bloom and change in flavour.

22. Moisture Problem In processing powdery foods (health foods like juice concentrates, protein supplements, soup powders, cocoa as well as gelatines, dehydrated soft drink concentrates, instant coffee powders and milk powders) moisture in the surrounding air cause lumping or caking causing the tiny particles to stick or cluster together, thus inhibiting their free flow in the manufacturing or packaging process. Many granular or powdered materials are transferred to packaging via high velocity air streams. This process is commonly referred to as pneumatic conveying or just airveying. For food handling, the efficiency of transporting powdered, granulated or flaked materials by high velocity air streams is significantly improved by drying the air.

23. Solution Dehumidifiers lower the moisture content of the surrounding maintain RH as low as 1% at a constant level regardless of the ambient condition during the production, storage and packaging Moisture control is essential in every segment of the food industry in the spheres of Storage, Production,Packaging,Processing and Low temperature drying

24. FAQs What is the use of a dehumidifier? And where is it installed ? Dehumidifiers reduce the moisture from the air, making it dry. Dehumidifiers are generally installed in process-areas like pharmaceutical companies and drying equipment, where low humidity is required. Estimate the loss occurring due to wastage of food due to fungal growth, moisture or mould formation ? Almost 30-40% of fresh fruits and vegetables produced are wasted due to decaying or fungal growth (happens when proper storage facility is not provided) In India, only 2% food is processed from the total food production, the rest 98% is supplied in the market, out of which almost 48% is decayed. in developed countries, 70% of food produced is processed, which increases the shelf life of the food product .

25. FAQs There were instances when worms were found in a chocolate produced by a well-known company. What role can dehumidifiers play to avoid such happenings? That instant might have triggered due to a number of reasons. If there is an external force of insects in the food product, they can multiply if proper conditions are not provided. Second, there could be a possibility of the growth of insects from within due to wet surface areas. The vendors must have lowered guards and hence the quality conditions must have been missed. De-humidifiers play a role in creating hygienic conditions by absorbing water from the air.

26. FAQs India being an agricultural country, what can be the contribution of Bry - Air dehumidifiers to protect food grains from insects? In India grains are stored at Central Warehousing Cooperation or in the open with a plastic covering. In this process the grains at the bottom get spoilt. Food Corporation of India estimates that loss to be around 3-5%. Worldwide, storage is done in silos. Dehumidifiers are installed on these silos. Silos can prevent losses that occur during drying (moisture loss results in weight loss and the farmers get paid for a lesser quantity), during transit as well as losses that occur when the stocks in the godowns become old.
