What is a sandwich pot?

A sandwich pot, also known as a steam pot, digester, or sandwich steam pot, is a specialized device specifically designed for efficient cooking and food processing. Its main characteristics and working principles are as follows:

Structural features: Double-layer structure: The core of the sandwich pot lies in its unique pot body structure, which is composed of two layers inside and outside the pot body. The inner pot is in direct contact with the ingredients,

usually made of stainless steel (such as SUS304) to ensure food safety and corrosion resistance; The outer pot wraps around the inner pot to form a mezzanine space.

Steam heating: The sandwich space is designed as a passageway for steam to circulate and transfer heat to the inner pan by heat conduction, thus heating the material inside the pan. This indirect heating method helps to avoid local

overheating or scorching of ingredients caused by direct flame, ensuring a more uniform and gentle heating process.

Diverse design: Sandwich pans are available in a variety of styles to suit different needs, including stationary (non-tilting), tilting (tilting for dumping or cleaning), and stirring (equipped with a stirring device for cooking or processing

that requires even mixing). In addition, according to the different heating sources, the sandwich pot can be divided into electric heating sandwich pot, steam heating sandwich pot, gas heating sandwich pot, electromagnetic heating

sandwich pot and other types.

Performance advantage: Large heating area: Because the entire sandwich area between the inner pot and the outer pot is involved in heat exchange, the heating area of the sandwich pot is significantly larger than that of the traditiona

single-layer pot, which can transfer heat more effectively. High thermal efficiency: Through steam heating, less heat loss, high energy efficiency. Uniform heating: the steam flows around the pot body in the sandwich, so that the material

in the pot can be evenly heated from all around to the center, which is conducive to maintaining the consistency of product quality. Short boiling time of liquid material: efficient heating method makes liquid material reach boiling state quickly,

shorten cooking or processing time.

Accurate temperature control: By adjusting the steam supply or power input, the temperature in the pot can be accurately controlled to meet the temperature requirements of different ingredients or processes. Good safety: Indirect heating

reduces the risk of fire, and the equipment is usually equipped with a variety of safety devices, such as pressure control systems, temperature controllers, etc., to ensure the safety of the operation process.

Application: Sandwich pot because of its efficient and controllable heating characteristics, widely used in all kinds of food industrial production and catering service industry: food processing: confectionery, pharmaceutical, dairy, wine, pastry,

preserves, beverages, canned, pickled flavor and other processing process, for boiling, cooking, concentration, sterilization and other steps. Catering services: Large restaurants, canthouses and other places are used for batch cooking operations

such as soup, cooking, meat stew, porridge, etc., which helps to improve meal efficiency and food quality, while reducing labor intensity. Sandwich pot is a kind of professional cooking equipment that uses steam to circulate heating between

double boiler bodies. It has the advantages of large hot area, high efficiency, uniform heating and easy temperature control, etc. It is suitable for all kinds of food processing and catering cooking.
