By adopting the instant freezer, thorough cleaning can be realized, the cleaning time is reduced, and the normal production rhythm is ensured.
The main structure of the instant freezer is the structure of the instant freezer which is generally adopted in the market at present.
As can be seen from fig. 1 of the patent, the height of the pumping chamber is high.
During the quick-freezing process of the coarse cereals, the coarse cereals are packaged by a vacuum bag, the thickness of the coarse cereals is not large, and the quality of the coarse cereals is smaller than that of fishes and meats. If a door curtain for blocking nitrogen is installed, the coarse cereals are not easy to be smoothly conveyed along the conveying belt. One solution that may be used is a curtain-less design, but the curtain-less design results in nitrogen gas easily escaping from the input port.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a no door curtain tunnel type frozen machine for five cereals quick-freeze, this frozen machine does not have a door curtain, can supply the five cereals wrapping bag to carry smoothly into to nitrogen gas can not follow input port and delivery outlet and escape.
In order to achieve the above object, the utility model provides a following technical scheme: a non-door curtain tunnel type instant freezer for quick freezing of coarse cereals comprises a body, a shell arranged on the body and a conveying belt arranged in the shell; the shell is connected with a liquid nitrogen input pipe, and a nozzle connected with the liquid nitrogen input pipe is arranged in the shell; a gap with the thickness consistent with that of the coarse cereals to be quickly frozen is arranged between the bottom of the air extraction bin and the conveying belt; and the air pumping hole of the air pumping bin is positioned at the bottom of the air pumping bin.
In the above-mentioned non-door curtain tunnel type instant freezer for quick-freezing of the coarse cereals, the height of the air-pumping bin is less than or equal to 1/2 of the height of the shell.
In the curtain-free tunnel type instant freezer for quickly freezing the coarse cereals, the air pumping bin has a structure with a wide upper part and a narrow lower part; and an air exhaust hose is arranged at the top of the air exhaust bin.
In the curtain-free tunnel type instant freezer for quickly freezing the coarse cereals, the air exhaust hose is fixedly connected with the top of the air exhaust bin through the hoop.
In the curtain-free tunnel type instant freezer for quickly freezing the coarse cereals, the section of the air extraction bin along the conveying direction of the conveying belt is in a right trapezoid shape or a right triangle shape.
In the curtain-free tunnel type instant freezer for quickly freezing the coarse cereals, a forced convection device facing a conveying belt is arranged in the shell.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses design the input port and the delivery outlet design height of material very low, only supply the good five cereals of vacuum packaging to get into, the design of no door curtain avoids the door curtain to stop the wrapping bag outside the door curtain, and the extraction opening design in the storehouse of will bleeding is in the bottom in the storehouse of bleeding, directly is close to the clearance like this (the input port and the delivery outlet of material promptly), can avoid the interior nitrogen gas of casing to escape from the clearance.
Drawings
Fig. 1 is a front view of embodiment 1 of the present invention;
fig. 2 is a side view of the air extraction bin and the conveyor belt according to embodiment 1 of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example 1
Referring to fig. 1-2, a curtain-free tunnel-type instant freezer for quick-freezing coarse cereals comprises a body 9, a shell 1 arranged on the body 9, and a conveyor belt 2 arranged in the shell 1; the shell 1 is connected with a liquid nitrogen input pipe 3, a nozzle 4 connected with the liquid nitrogen input pipe 3 is arranged inside the shell 1, and two sides of the end part of the shell 1 are provided with an air pumping bin 5; a gap 6 with the thickness consistent with that of the coarse cereals to be quickly frozen is arranged between the bottom of the air extraction bin 5 and the conveyer belt 2; the air pumping opening 10 of the air pumping bin 5 is positioned at the bottom of the air pumping bin 5.
In this embodiment, the design heights of the input port and the output port of the material are designed to be very low, only the vacuum-packed coarse cereals enter, the design without the door curtain prevents the packaging bag from being blocked outside the door curtain, the air exhaust port 10 of the air exhaust bin 5 is designed at the bottom of the air exhaust bin 5, and therefore the air exhaust port is directly close to the gap 6 (namely the input port and the output port of the material), and the nitrogen in the shell 1 can be prevented from escaping from the gap 6.
In this embodiment, the height of the pumping chamber 5 is less than or equal to 1/2 of the height of the casing 1, and the lower the height of the pumping chamber 5 is, the higher the pressure of the pumping port 10 is, the less the nitrogen gas is easy to escape from the gap 6.
In this embodiment, the air extraction bin 5 has a structure with a wide upper part and a narrow lower part; the top of the air exhaust bin 5 is provided with an air exhaust hose 7. The design that the upper part of the air pumping bin 5 is wide and the lower part of the air pumping bin is narrow can improve the pressure of the air pumping hole 10 and prevent nitrogen from escaping from the gap 6. Preferably, the section of the air extraction bin 5 along the conveying direction of the conveying belt 2 is a right-angled trapezoid.
Preferably, the air exhaust hose 7 is fixedly connected with the top of the air exhaust bin 5 through a clamp 8, and a forced convection device facing the conveying belt 2 is arranged in the shell 1.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
