Chapter II. Working Principles and Overview
2.1 Main uses and characteristics
Stainless steel gas heating sandwich pot is widely used in candy (soft candy, hard candy), dairy wine, pastries, beverages, preserves, cans and other food processing. It can also be used in large restaurants or canteens to boil soup, stew, porridge and so on. It is an excellent equipment for food processing to improve quality, shorten time and improve working conditions.
This pot uses gas as heat source, heating the heat conducting oil (or other heat transfer medium) in the interlayer by generating heat, and then heating the material of the inner pot through heat transfer. In addition, the inner gallbladder can also be directly heated (such as porridge and other non-sticky pot materials), which has the following advantages:
1、Full combustion, smokeless and dust-free, a small amount of carbon deposition, no environmental pollution.
2、The flame temperature can be adjusted at will, and the maximum temperature is about 300 C.
3、Strong energy-saving, fierce fire, thermal efficiency than similar products increased by about 25%.
4、Fuel: liquefied petroleum gas, pipeline gas, natural gas and oil are strictly prohibited.
5、Gas consumption: 20% lower than similar products.
According to the different characteristics of the material, the inner pot body is made of acid-resistant and heat-resistant austenitic stainless steel SUS316L or SUS304. The sandwich can be made of SUS304 stainless steel or Q235-B carbon steel according to user's requirements. In addition, in order to avoid heat loss, an insulating layer is designed (according to the temperature, polyurethane foaming insulation with high density and excellent thermal insulation performance is selected, or compactness is selected). Glass rock wool insulation layer with good properties and high temperature resistance.The outer insulation layer is protected by SUS304 stainless steel wrapping. It has beautiful appearance, easy installation, convenient operation, safety and reliability.
2.2 Main Structure and Process Flow of Products
2.2.1 The main body of the equipment is hemispherical structure, consisting of heightening ring, hemispherical pot body, stove head, leg or bracket, and various functional nozzles. The sandwich pot with stirring is equipped with motor and stirring impeller.
Supporting foot type: trough support type.
Stirring paddle type: ordinary stirring (anchor type) and scraping bottom stirring, scraping edge material for PTFE. Pot body with mixing device: top central mixing, reducer output shaft and mixing propeller shaft using looper connection, easy to disassemble and clean. Tilting type sandwich pan body can tilt up to 90 degrees, and the tilting mode is manual.
A、Direct heating of inner liner by flame
Tilting type is mainly composed of pot body, furnace head and tilting device. The maximum inclination is 90 degrees (Fig. 1)；
Tilting belt stirring mainly consists of pot body, furnace head, stirring device and tilting device (Fig 2)；
B、Flame heating jacket
The tilting type is mainly composed of a pot body, a furnace head and a tilting device with a maximum tilt of 90 degrees (fig. 3).；
Tilting belt stirring is mainly composed of pot body, furnace head, stirring device and tilting device (Figure 4).；2.2.2 The general process flow for operation of this equipment is as follows:：Rinse the inner wall of the pot→Adding water of material and process proportion to the pot（Tilting sandwich pot needs to be level first）→Open the furnace intake and ignite, heat the pot body to the material to the temperature required by the process.→Keeping the material temperature in the pot for a period of time can stop the air intake and discharge when the technological requirements are met.→Cleaning equipment.（The specific process is formulated by the user according to the material characteristics.）

Chapter IV. Operational Guidelines
4.1 Equipment installation
4.1.1 Generally, the equipment does not need to be fixed, as long as it is placed on a flat and solid ground. It can also be fixed with anchor bolts. There are holes in the support foot or the bottom of the support for bolt piercing.
4.1.2 The jacket needs to add heat conducting oil to the interlayer: close the heat conducting oil outlet, open the non-condensable gas outlet valve, the interlayer of the pan body has an external thread joint, can screw a matching elbow upward, place a funnel to add heat conducting oil to the pan (generally 320 type heat conducting oil). Refuel until the condensable gas outlet has just begun to overflow the heat conducting oil. Keep in mind that the interlayer must be connected with the atmosphere. When heated, the interlayer should be atmospheric pressure.
Reference to the amount of heat conducting oil added for each type:
model | Heating area（㎡） | Heat transfer oil quantity （L） | Power and Root Number （KW×Z） |
DG50 | 0.45 | 30 | 3×3 |
DG100 | 0.58 | 36 | 3×3 |
DG200 | 1.13 | 45 | 5×3 |
