Description

Technical Field

[0001] The invention relates to a fume purification module of cooking equipment, belonging to the technical field of cooking equipment. Background Art

[0002] A kitchen cart is a van-like "special vehicle" used for preparing meals. It's equipped with a stove, water supply, food storage, ventilation, and fire safety features. It's generally categorized into three types based on its purpose: stationary kitchen carts, which are used for long-term, daily meal preparation; fast-food kitchen carts, which provide quick catering services for gatherings, sports competitions, and large-scale mass events; and multi-purpose kitchen carts, which serve both meal preparation and other purposes.

[0003] Military kitchen carts are specialized vehicles used to provide food and beverages in the field. They support troops during military exercises, disaster relief operations, and field training. These carts are equipped with cooking equipment, and currently, traditional exhaust systems are used to exhaust fumes from these cooking equipment. These carts typically provide logistical food and beverage support for the entire unit, processing large quantities of food. However, due to the limited space available in these carts, traditional exhaust systems are ineffective, with smoke easily accumulating inside the cart, causing oily fumes to form and become difficult to clean. Exhaust temperatures are often too high, and the fresh air temperature is low.

[0004] Therefore, it is urgent to propose a fume purification module for military cooking equipment to solve the above technical problems. Summary of the Invention
