METHOD AND APPARATUS FOR PERIODIC PRODUCTION OF FRIED BULK FOOD PRODUCTS, IN PARTICULAR, NUT NUCLEI AND OIL CROP SEEDS Russian patent published in 2004 - IPC

FIELD: thermal treatment of food products in food-processing and other branches of industry. SUBSTANCE: method involves placing product into frying vessel made in the form of tank; heating product; mixing product by mixer. Frying vessel is made composite. Tank-shaped frying cavity of frying vessel is formed by joining of at least two individual forming devices, including wall forming and bottom forming devices. Bottom forming device is made movable and adapted for rotation and/or linear movement. Area of bottom forming surface or total area of bottom forming devices is at least πD²/4, where D is diameter of round tank-shaped frying cavity of frying vessel. Upon completing of frying procedure, at least one forming device is rotated and/or moved in linear direction and product is discharged from frying vessel. Apparatus has frying vessel made in the form of tank, base, mixer, and heating device. Method and apparatus allow product to be uniformly fried owing to reduced possibility of excessive frying and burning of product due to reduced time for discharge of total volume of fried product from frying vessel and damage to product during discharge thereof from frying vessel to be reduced due to minimal urging forces applied to product and reduced mixing time. EFFECT: improved quality of fried product by minimized processing time and reduced damage to product. 25 cl, 4 dwg
