Industrial fryers

Industrial fryers generally are of two types (1) those who sell all the purchased oil with the product, and (2) those who must recondition and occasionally dispose of oil. Requirements for the selection and use of frying oils in these applications differ.175 Industrial snack food fryers, designed to use all the oil, are equipped with clean-out systems and inline filters. In theory, they should be able to operate indefinitely, only adding make-up oil as needed. In clean label, operations, company policy dictates that no, or minimum, additives can be used. Typically, company personnel periodically inspect and...

Industrial fryers are equipped with pumps for continuous recirculation of the oil through external heaters and filters. Fresh oil (makeup oil) is added automatically to replace the oil absorbed by the food and maintain the desired level in the fryer. 

Adsorption treatment requires proper filtration of oil. Spent adsorbents, if left in the oil, can catalyze further reaction in oil. A batch filtration system could be adequate for a small size restaurant type fryer. However, for large industrial fryers, this can be expensive. A continuous slip stream filter system could be quite small, relative to the size of the fryer. However, this adds extra volume of oil to the system, increasing oil turnover time. This must be taken into account as part of the total picture.
