1996 APV Crepaco Amerio Manual Contact Plate Freezer. Model: 15-A. Refrigerant: recirculated ammonia (R-717). Number of plates: 17. Plate material: aluminum. Approximate capacity rating on hamburger patties: 1419 lbs./hr. based on 1/4 inch thick patties, 1/4 lbs. each, going from a starting temperature of 40°F to a core temperature of 0°F, where plate temperature is -45°F and approximately 18 tons of refrigeration is used. Amerio contact plate freezers offer an alternative to freezing, as products come into direct contact with plates that freeze products to a core hardness of 0°F at an average of one inch per hour. Not only is this method less expensive than air blast or cryogenic alternatives, but other benefits include: preserved product texture, uniformity and nutrient retention as smaller ice crystals are formed and damage to cells is virtually non-existent. Initially used in fish processing, other applications include meats, vegetables, ice creams and bakery products. Control Box: 220 / 208 bolt 3-phase. Plate dimensions: 5 ft. 1 in. L x 3 ft. 8 in. W.
