Recherche hi- tek engineers offers reactors engendering heat transfer and mixing in a one step operation. Processes involving transfer of heat can be problematic if the products are particularly sensitive to temperature. There are a number of products, which under the influence of temperature can change characteristics in an undesirable manner. Such products are found particularly in the chemical. Pharmaceutical, agro, food, adhesives and plastic industries. Such undesired secondary reaction may differ from product to product. It could cause discoloration, change the taste in foodstuffs, resulting in adverse alterations to essential attributes of the product. This leads to resultant damage in the product quality. The problem requires a study of the applied temperature and the time during which the product is under the influence of the temperature. The process engineering characteristics are closely studied before designing the htr.
