Once your production facility of food has crossed your storage, it is now important to look for tanks with larger storage for food produce and chemicals for clean-in-place. You will get multiple options for a good food grade tank but it is important to check if it can cope up with the greatest challenges such as full-drain capabilities, FDA requirements, and cost. Here are the important tactics to consider while selecting a food grade tank –
- Full drain- Food processing companies are often seen facing the challenge of full-tank drainage. This is due to the reason that a little level over food can cause massive amount of damage to food batches or CIP soaps or additives. It is, thus, essential to extract soap or food out of the food grade tank and start all together again. There are manufacturers of food grade tank who claim to drain 100% of leftovers. However, these tanks fail to do as committed. The root of the problem is the below of the tank that is about half inch in measurement that prevents full drainage.
Do not forget to ask your manufacturers about the inserts, capable of causing real damage to your produce. While the tank is being manufactured, a metallic insert is added to the mold to get encapsulated in the tank’s sidewalls. After the mold is finished, it is cleaned and a rubber grommet is fitted onto it. But these fittings can result in leaking making the insert prone to corrosion. Since the insert is made of different material than that of the tank, both of them suffer different rates of contraction and expansion. You may also find cracking around the insert.
Try to look for hundred percent drainage food grade tank so that you never look twice this problem.
- Storage tanks in compliance with FDA – Customers who are keen on buying a food grade tank, are often seen querying about the FDA requirements. FDA never actually approves machinery or tanks and only deals with approval of items that are added into food. However, FDA does not approve any type of equipment in processing of food. Rather it has introduced a number of requirements that any equipment used in food production should be able to fulfill.
- Tank material – In case you are not intending to store any harsh chemical, stainless steel tanks make the perfect choice of food grade tank. It is often seen that stainless steel is perfect for meeting the temperature as well as pressure constraints. However, it is charged more than we can see in other tank materials. Also, it requires maintenance for lifetime. When it comes to inner surface, it has more pores than any other material which encourages the growth of bacteria. On the other hand, polished stainless steel is comparatively less porous and resists bacteria on the inner surface of the tank. But, the polished stainless steel food grade tank are available at a hefty price. There are other material available in food grade tanks giving an outstanding performance for years such as cross-linked polyethylene tanks.
