Description
Technical field
The present invention relates to integrated hot air roasting machine, be used for the baking of cereal, beans, spices, oily seed and ready to-eat snack foods/roasting.Hereinafter integrated hot air roasting machine is called device.Device of the present invention relates in particular to and uses flue gas, is used to dry by the fire/bake the integrated hot air roasting machine of cereal, beans, spices, oily seed and ready to-eat snack foods, it has strengthened organ sensory characteristic (organoleptic properties) and order is finished in single machine baking, maintenance (resting) and cooling down operation.Use this device product processed color and humidity evenly and have other sense quality, and can under the condition of health, handle material in a continuous manner.
Background technology
In the time can obtaining continuously to dry by the fire/to bake the device of cereal, beans, spices, oily seed and ready to-eat snack foods, can reduce hand labor, and produce the sanitation and hygiene do not have husky and ash, color and luster evenly and toast uniform final products.Because hot gas cycle, therefore this device is a high energy efficiency.Find that by retrieval the patent No. is that the Deutsche Reichs Patent of DE 3116723 C2 discloses batch-wise roaster.Be in the patent of 0039-4653 in the patent No. only, fluidized bed roaster (Weyell, 1997) is used vibration mode.Equipment among the Vibro (Germany) is used to toast fibert, coconut powder etc.Yet this equipment is batch-wise equipment, and does not use flue gas to toast.
At present, roaster is batch-type roaster, continuous husky roaster, rotary roaster and jet-propelled roaster.More than all in the roasters, the unit operations of heat treated, temperature/moisture stabilization and ensuing cooling is all independently finished.The subject matter of these roasters is can not toast equably with painted, produces burned and particulate blackening, and can be doped with sand and ash after processing, and these will cause producing low-quality product.These equipment are length consuming time in operation, and the operator need operate under the direct influence of flue dust and flame, and husky roaster is not suitable for the baking of spices such as picture capsicum, coriander.Under the situation that can be used for cereal, beans, spices, oily seed and ready to-eat snack foods are toasted continuously when proper device, can reduce the labour, and produce final products sanitation and hygiene and that have uniform baking color and luster that do not have sand and ash.Recognize its importance and necessity, the Mysore of center food Institute for Research and Technology (CentralFood Technological Research Institute) successfully develops a kind of device that is used to toast cereal, beans, spices, oily seed and ready to-eat snack foods.
Up to the present, the baking of cereal, beans, spices, oily seed and ready to-eat snack foods/roasting processing can realize by slewing and transfer equipment.Slewing has standard ovens, is used to toast the food sheet (flake) of all types in the breakfast food industry.Toast the fixed position that food sheet is difficult on the flat board, thereby cause product colour inhomogeneous.When rotary oven makes food sheet be suspended in the air of heating, can be equably all surfaces of food sheet be heated, it is evenly toasted and have uniform color.Slewing comprises thermally insulating housing and inner rotary cylinder.Inner casing is made by ordinary carbon steel, and shell is made by mild steel and be suitably heat insulation.The inner casing of porous is used for the big food sheet of picture cereal and wheat, and the cylinder of atresia is used to handle miscellaneous goods.The key character of rotation type roasting plant is to have push rod in the inboard of inner cylinders, is used for product is evenly mixed.The belt roaster is used for the large article that thickness is 6-20mm, and the product that will break into pieces in cylinder.These are very simple equipment, and wherein conveyer moves through oven cavity, and can directly or indirectly light.The roaster that efficient is higher is a jet zone unit, and wherein hot gas being exerted pressure makes it pass through nozzle, and nozzle directly is sprayed onto high-speed air on the product.The product of Chan Shenging is more even than the product of conveyor roasted like this.But jet zone unit is not suitable for toasting oily seed and breakfast food etc., will diminish the final shape of product because air at a high speed sprays.
Use the defective of the roaster of above type to be:
* toast inhomogeneous;
* can not in single device, toast cereal, beans, spices, oily seed and breakfast food;
* can not toast non-classified material;
* Hong Kao material will have uneven color;
* will have in the product and burn/particulate of blackening;
* final products will be subjected to pollution husky and ash;
* operate length consuming time, and the operator must emit flame and flue dust to carry out work;
* the unit operations as maintenance and cooling etc. needs separately finish separately;
* husky roaster is not suitable for for example spices of capsicum and coriander etc.;
* jet district roaster can diminish the net shape of product, and is not suitable for the spices of breakfast food and picture capsicum; And
* the hot gas that these equipment can not recycling consumption.
