Description

 TECHNICAL FIELD

 The present invention relates to food processing machinery, and in particular, to a meat roaster for roasting meat in the process of conveying meat on a continuously running conveyor. Background technique

 Existing meat roasting equipment can basically be divided into two categories, one is manual cooking, such as a rectangular charcoal burning box, or an electric oven using electric heating, which are all manually operated and cannot be continuously operated. Therefore, the productivity is low, the energy consumption is large, and the uniform and stable baking quality cannot be guaranteed.

 Chinese utility model patent document ZL 93200844. 5 discloses a barbecue oven, in which a to-be-baked object mounted on a rotatable barbecue rack can be rotated in the oven by means of a transmission mechanism in order to control and 'improve the to-be-baked object' The degree of baking uniformity. However, this barbecue grill still adopts the intermittent operation method, and the position of the object to be grilled does not move. When the meat is loaded and unloaded, the furnace door must be fully opened, so its productivity is not high. When the furnace door is opened, the heat loss is large. In addition, since the temperature of each part in the barbecue oven is difficult to reach the same level, there is still a quality problem that the roasting degree cannot be exactly the same. Summary of the Invention

 ^ The purpose of the invention is to overcome the shortcomings of the existing meat roasting equipment, and to provide a mechanized continuous operation capable of continuous operation, high production efficiency, low energy consumption, uniform and stable quality of roasted meat, good labor conditions and convenient operation. Meat roaster.

 A further object of the present invention is to provide a continuous meat hob roasting machine with a small footprint and a higher heat energy utilization rate.

In order to achieve the above object, the continuous meat roasting machine of the present invention includes the following components-various parts and components for supporting and installing the meat roasting machine, and a body made of steel. Pass for loading and unloading of meat to be roasted and roasted Outside the opening of the food, it is basically closed;

 A heating element which is arranged inside the body and provides heat for roasting meat;

 In addition, there is a heating area in the body that can carry the meat continuously and uniformly through the heat of the heating component, 4 a meat conveying mechanism that successfully roasts the meat; and

 A meat rotating mechanism that causes the meat to rotate at the same time as it moves through the heating zone so that each part of the meat is baked more evenly.

 When the meat conveying mechanism is designed to reciprocate in a overlapping manner within the heating area of the heating component for thousands of times, the footprint of the equipment can be greatly reduced, and the utilization rate of thermal energy can be further improved.

 The thermal energy used in the heating member of the present invention may be electric energy, or may be thermal energy generated by burning a gaseous fuel, a liquid fuel, or a solid fuel.

 Meats that can be baked on the continuous meat roaster of the present invention include beef, lamb, chicken, fish, and all meats of livestock or poultry. When the roasted meat is kebabs, according to years of roasting experience, if roasted with the heat of burning charcoal, the roasted mutton has a special flavor and is deeply loved by consumers.

 In view of this, when the present invention uses a charcoal-burning heating member, the heating member is composed of a charcoal-containing furnace chamber arranged along the length of the machine body in the lower part of the above-mentioned body, and Composed of grey buckets. The furnace is composed of a furnace side plate, a bottom plate with a vent hole, and a furnace end plate. At the same time, due to the special needs of natural ventilation when burning solid fuels, several appropriately-sized air inlets should be opened at the bottom of the basically closed body, and several exhaust chimneys should be set at the body part, and each chimney should be set There are regulating valves for adjusting the displacement.

In addition, when the thermal energy is generated by electric energy or burning gaseous fuel or liquid fuel, the temperature distribution in the heating area of the body is relatively uniform. At this time, if the meat is a lamb skewer or chicken skewer strung on a long string, etc. The kebabs can pass horizontally through the heated area. However, when the fuel is a solid fuel in the hearth, such as charcoal, the combustion flame in the hearth will show a high flame in the central area and a low fire depression on both sides. Therefore, at the same height above the hearth, The temperature in the center must be higher than the temperature on both sides. If the skewer (or long-shaped meat) also passes horizontally above the hearth, then the front of the skewer It is not the same as the back-end meat, which will affect the quality of the product. Therefore, in the latter case, the skewers should be tilted at an angle to the horizontal line as they pass through the heated area. Make the meat skewers close to the central area of the hearth leave the oven at a higher height than the meat farther away from the central area of the hearth, so that all meat on the skewers can be basically roasted to the same extent, and the product has a stable and consistent quality. quality.

 When using charcoal to roast various skewers, the angle between the skewers and the horizontal line when passing through the heating area is generally 5 ° ~ 25. about.

 When the type of meat to be roasted is different, or the size of the meat is different, the time and temperature for roasting should also be different. Therefore, the transmission mechanism driving the meat conveying mechanism should have the function of speed regulation, such as using a DC or AC speed regulating motor or a stepless speed governor, so as to control the roasting of the meat by controlling the moving speed of the meat through the heating area time. At the same time, set a thermometer (such as a thermocouple thermometer) in the heating area to observe and control the temperature in the heating area. Furthermore, the temperature of the heating area detected by the thermometer can be used as a parameter to automatically control the working process of the heating component and the moving speed through the heating area.

 In order to maintain a stable temperature range and save energy in the heating area, an insulation layer can be added to the inner wall of the body surrounding the heating area. The insulation layer is usually fixed on the body and made of heat-insulating materials (such as asbestos, slag wool, fiberglass, etc.).

 When using charcoal as fuel, it is best to open openable observation windows on the upper sides of both sides of the body. The center of the observation window is inlaid with high temperature resistant glass. When closed, you can observe the roasting of meat and the burning of charcoal through the observation window. By opening the observation window, you can add charcoal to the charcoal-containing furnace through the observation window and adjust the combustion of charcoal.

 The aforementioned meat conveying mechanism may adopt a sprocket-chain transmission mechanism or a sheave-wire rope transmission mechanism. The chain in the aforementioned sprocket-chain transmission mechanism may be a roller chain or an endless chain formed by chain links. The device for inserting meat is fixed on a chain plate, a chain link or a copper wire rope.

The above-mentioned meat conveyors provided on the meat roasting machine of the present invention may be one, or a plurality of them may be arranged side by side, and the productivity will be further improved by double-double-cylinder, and thermal energy can be better utilized.
