What is the advantage of scraped surface heat exchanger?For large installations where vacuum crystallization may seem attractive, scraper crystallizers are cost effective. The design minimizes shear stress on fine crystals, but is robust enough to handle hard crystals.
The evaluation of margarine and ghee products is usually done by means of baking experiments. The baking test of flaky margarine is evaluated by measuring the height of flaky margarine and the evenness of laminated structure. The operability of margarine products is not just based on the plasticity of the product, nor can it be simply determined by kneading. Sometimes margarine's initial evaluation is poor, but it shows good operability when baking. The habits of professional bakers often influence how products are evaluated.
Pastry margarine must be plastic and steady. The technics flow of producing pastry margarine can be arranged very easy by tubular chiller (tubular scraped surface heat exchanger). During the deep-processing of oil, cooling has significant influence on the crystallization of pastry margarine. Different margarine needs different process and tempering condition. Key words : pastry margarine; chilling drum; tubular chiller, scraped surface heat exchanger, margarine production.
High quality processed pressure gage and SEW motor is equipped with scraped surface heat exchanger, high processed parts guarantees the assembling precision, and brand motor keep the machine to be steady.
The new designed scraped surface heat exchanger (SSHE) have two advantages compared with the previous machine:1.High rotating speed, about 1.34 times of European scraped surface heat exchanger;2.Low annular gap, 1mm less than European scraped surface heat exchanger;
