Food grade PC material, which does not soften when heated, and has lower thermal conductivity, can greatly reduce heat loss and prevent water evaporation during long-term slow cooking.With unit identification, convenient and accurate water quantity. With a size of 66*90mm, it is suitable for various slow boilers. The light transmittance is close to that of glass, which is beautiful and generous, and is convenient to observe the slow cooking process at any time. It is not easy to slip on the wet desktop. It is more convenient to take it at hand. Even if it holds more weight, it can be taken comfortably.6 liters: suitable for home use, can cook about 1-4 pieces of steak at a time.11 liters: suitable for home use, can cook about 1-7 pieces of cowhide at a time.22 liters: suitable for commercial use, can cook about 1-15 steaks at a time.All three water tanks have covers, and the opening size is 66 * 90mm, which is generally used in most machine slow cooking machinesThe water tank is a high quality PC material. It has the characteristics of high transparency, light weight, impact resistance, sound insulation, heat insulation, inflammable and anti-aging. It is a high-tech, comprehensive function, excellent energy saving and environmental protection type plastic.Energy saving, environmental protection and heat insulation: the lower thermal conductivity of PC material can greatly reduce heat loss and prevent water evaporation during slow cooking for a long time, and, It is better to match with stainless steel steak rack and isolation rack.
