Description

Be used for food cold extrusion former

Technical Field

The utility model relates to a food processing technology field especially relates to a food extrusion equipment, specifically indicates one kind and is used for food cold extrusion former.

Background

The existing cold extrusion molding equipment has a smaller machine barrel, the screw pitch of the adopted material conveying screw generally adopts a uniform screw pitch structure, and after food materials are added, the problems of unsmooth extrusion molding, serious screw blockage and the like generally exist, so that the equipment cannot be applied to the processing of extrusion molding products in the food industry. When the materials are added and extruded out smoothly, the problems of material blockage, low extrusion speed, motor load and the like of the screw are caused. And in severe cases, the product cannot be extruded, and the continuous processing of the material cannot be realized.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to prior art's not enough, provide a novel cold extrusion former that is applicable to food processing, can solve the problem of material putty and improved shaping quality and output after adopting this equipment.

The utility model provides a, provide a be used for cold extrusion moulding equipment of food, include the barrel and establish the screw rod in the barrel, the pitch of screw rod be variable pitch, the pitch is from front end to terminal including the gradually little I district of pitch, pitch keep district and the gradually little II of pitch distinguish the three-section region, the screw rod reduces gradually at the gradually little while thread helix angle of pitch, the terminal angle lead angle of the helix angle of the terminal screw thread of screw rod is 7 ~ 8 degrees.

As an improvement, a material temporary storage area is additionally arranged in a machine barrel storage space of the machine barrel.

Preferably, the pitch of the zone I is gradually reduced from 100mm to 70mm, the pitch of the zone I is kept unchanged at 70mm, and the pitch of the zone II is gradually reduced from 70mm to 40 mm.

After the scheme above the adoption, the utility model discloses design into variable screw with the pitch of screw rod, make the pitch evenly change, the pitch front end diminishes to the end gradually to the extrusion of the food material that makes is more powerful, in addition, screw rod thread angle changes from front end to end gradually, and terminal angle is close perpendicularly with the barrel, and this makes the material extrude the in-process more level and smooth, and the barrel increases barrel storage space, makes the material have the region of keeping in, avoids appearing the problem that long-pending material made the material jam in the screw rod.

To sum up, the utility model discloses effectively solved the cold extrusion course of working material of food and extruded unsmooth, putty scheduling problem, made the product extrude the continuation strong, extrusion speed is fast, has improved equipment stability and product quality, has improved the energy consumption and has utilized than.

Detailed Description

In order to clearly illustrate the technical features of the present invention, the present invention is further illustrated by the following embodiments in combination with the accompanying drawings.

As shown in fig. 1 to 3, a cold extrusion molding device for food comprises a barrel 2 and a screw 1 arranged in the barrel 2, wherein the screw 1 has a variable pitch, the pitch is divided into three sections from a front end to a tail end, the three sections include a pitch gradually decreasing section I, a pitch maintaining section and a pitch gradually decreasing section II, the pitch of the screw 1 gradually decreases while the pitch decreases, and the tail end angle of the pitch of the tail end thread of the screw 1 increases by 7.8 degrees.

In this embodiment, barrel storage space of barrel 2 add material temporary storage area 3, the gradually district's pitch of pitch gradually become 70mm by 100mm, the pitch keeps the district and keeps the pitch 70mm unchangeable, the gradually district's pitch of pitch II gradually becomes 40mm again by 70 mm.

Finally, it should be further noted that the above examples and illustrations are not limited to the above embodiments, and technical features of the present invention that are not described in the present application can be implemented by or using the prior art, and are not described herein again; the above embodiments and drawings are only used for illustrating the technical solutions of the present invention and are not intended to limit the present invention, and the present invention has been described in detail with reference to the preferred embodiments, and those skilled in the art should understand that changes, modifications, additions or substitutions made by those skilled in the art within the spirit of the present invention should also belong to the protection scope of the claims of the present invention.
