Double-template discharge device of puffing machine

Abstract

The invention discloses a double-template discharge device of a puffing machine in the field of the grain machinery and the forage machinery. The double-template discharge device comprises a fixing bracket, a venturi tube, a diversion cone and a forming template, wherein the template is provided with a plurality of die holes, the fixing bracket is arranged one side in the venturi tube, a template bracket is arranged between the venturi tube and the forming template, the diversion cone is fixed at the center position on the template bracket which is faced to one side in the venturi tube, a pressure adjusting template is arranged between the venturi tube and the template bracket, the center of the pressure adjusting template is sheathed at the root of the diversion cone, the pressure adjusting template is provided with a plurality of through-flow holes, and the sum of the through-flow areas of the through-flow holes is larger than sum of the through-flow areas of the die holes. The discharge device adopts a double-template design, so that a stable space is guaranteed after the material passes through the pressure adjusting template, and the material is even in flow velocity, so that the even quality, the stability and the proper puffing degree of the final product are guaranteed; and the better puffing effect is obtained, and the yield is improved. The double-template discharge device can be applicable to the production of various puffed foods and forages.

Description

technical field [0001] The invention relates to a discharge device for extrusion and puffing equipment in the field of food and feed processing, in particular to a discharge device for extrusion and puffing equipment that needs to reduce the discharge pressure. Background technique [0002] Extrusion technology has long been widely used in the field of food and feed processing. The existing discharge device includes a fixed frame, the fixed frame is connected to one side of the Venturi, the other side of the Venturi is provided with a forming template, and the forming template is provided with a number of die holes, and the forming template is connected to the Venturi through a pressing plate. Fixed, the center of the forming template is provided with a diversion cone on the side facing the Venturi. During the working process of the extruder, the pre-cured material moves towards the discharge die hole through the rotatable screw. During the process from the feed port to the...

[0004] 2. In the case of the same high output, the difference in the flow rate of the material flow in the discharge device is more obvious. The flow rate in the middle of the forming template is fast and the flow rate at the periphery is slow, resulting in more obvious uneven product particle size. At this time, it is also necessary to limit the output. Meet product quality
