Description
Technical field
This utility model relates to freezing equipment field, is specifically related to the tunnel sealing device of a kind of split type liquid nitrogen tunnel freezer for aquatic products quick-freezing.
Background technology
Along with growth in the living standard, people are increasing to the demand of aquatic products, and due to aquatic products fishing season and the existence in closed fishing season, make fresh and living aquatic products cannot meet the demand of people, and therefore frozen fish commercially holds an important position.For ensureing the quality of frozen fish, many employing quick-freezing techniques, ammonia, freon or liquid nitrogen is utilized to freeze, wherein liquid nitrogen refrigerating energy quick freezing product and tide over ice crystal generate band, prevent big ice crystal from being formed in food cell and destroying cell wall, can preferably keep the original local flavor of product and quality, and environmental benefit is obvious, so liquid nitrogen refrigerating becomes the trend that current aquatic products are freezing.
Current liquid nitrogen aquatic products quick freezing unit is generally divided into cabinet type and tunnel type two kinds, and wherein tunnel type freezer belongs to streamlined production equipment, is suitable to the production of high-volume frozen fish.Existing liquid nitrogen tunnel freezer, generally comprises body, is provided with tunnel in body, is provided with conveyer belt and liquid nitrogen spray in tunnel, and during tape transport aquatic products, the liquid nitrogen utilizing liquid nitrogen spray to spray completes the frost to aquatic products.
Split type liquid nitrogen tunnel freezer, compared with integral type liquid nitrogen tunnel freezer, has cleaning, an advantage easy to maintenance, but existing split type liquid nitrogen tunnel freezer also to have freezing tunnel to seal tight, the shortcoming that the utilization rate of liquid nitrogen is low.
Utility model content
In order to improve the sealing property of split type liquid nitrogen tunnel freezer freezing tunnel, this utility model provides the tunnel sealing device of a kind of split type liquid nitrogen tunnel freezer.
The technical solution adopted in the utility model is as follows:
The tunnel sealing device of a kind of split type liquid nitrogen tunnel freezer, including lower support, adjustable for height upper machine body and freezing tunnel, one end of described freezing tunnel sets material inlet, and the other end sets material outlet；Described lower support is equipped with sealing baffle with the contact site of upper machine body both sides.
The upper end of described sealing baffle is arranged on described upper machine body, and described upper machine body lower edge the contact internal walls with described lower support are stretched out in lower end.
Described lower support inwall and vertical direction are 10 ~ 20 ° of angles, and described sealing baffle uses elastic component, and described lower end and vertical direction angle are less than described lower support inwall and the angle of vertical direction.
Described sealing baffle is made up of polylith short shutter.
A length of 10 ~ the 30cm of described short shutter.
It is equipped with active catch fan at described material inlet and material outlet.

Detailed description of the invention
In below in conjunction with the accompanying drawings, the utility model is described in further detail with embodiment.
In embodiment, as shown in Figure 1 and Figure 2, a kind of tunnel sealing device of split type liquid nitrogen tunnel freezer, including lower support 1, adjustable for height upper machine body 2 and freezing tunnel 3, one end of described freezing tunnel 3 sets material inlet 4, the other end sets material outlet 5, and described lower support 1 is equipped with sealing baffle 6 with the contact site of upper machine body 2 both sides.Lower support 1 of the present utility model and upper machine body 2 are in addition to the contact surface both relying on seals, sealing baffle 6 mainly by the two binding site seals, with seal good in ensureing freezing tunnel 3, increase the utilization rate of liquid nitrogen, reduce the cost of aquatic products quick-freezing.
In embodiment, as shown in Figure 2 and Figure 3, the upper end 62 of described sealing baffle 6 is arranged on described upper machine body 2, and described upper machine body 2 lower edge the contact internal walls with described lower support 1 are stretched out in lower end 63.This utility model is the most rotatable to be arranged on sealing baffle 6 on lower support 1.
In embodiment, as shown in Figure 2 and Figure 3, described lower support 1 inwall and vertical direction are 10 ~ 20 ° of angles, and described sealing baffle 6 uses elastic component, and described lower end 63 and vertical direction angle are less than described lower support 1 inwall and the angle of vertical direction.The present embodiment structure, utilizes the deadweight on upper machine body 2 to push down lower end 63, is allowed to fit with lower support 1 inwall, has sealing closely, and open convenient advantage.
In embodiment, as shown in Figure 4, described sealing baffle 6 is made up of polylith short shutter 61.Owing to the length of lower support 1 is longer, its linearity mismachining tolerance is the biggest, the sealing baffle 6 of the present embodiment uses multiple segmentation short shutter 61 close-packed arrays assembled, each position of sealing baffle 6 so can be made can to fit the inwall of lower support 1, it is ensured that preferably obturation effect.
In embodiment, as shown in Figure 4, a length of 10 ~ 30cm of described short shutter 61.The oversize obturation effect of short shutter 61 of the present embodiment will not, the shortest processing trouble the most easily make mistakes, 10 ~ 30cm belongs to preferred scope.
In embodiment, at described material inlet 4 and material outlet 5, it is equipped with active catch fan.The active catch fan of the present embodiment had both had preferable obturation effect, has portion to affect charging and discharging, is carved with the fridge of product turnover when being particularly suitable for.
In embodiment, as it is shown on figure 3, be provided with defrosting on the contact surface of described lower support 1 and upper machine body 2 to add heat pipe 7.During quick-freezing, because low temperature and the existence of moisture, on lower support 1 is frequent with the contact surface of upper machine body 2, frost occurs, cause lower support 1 cannot separate with upper machine body 2, the present embodiment is provided with defrosting on the contact surface and adds heat pipe 13, contact surface can be maintained in certain temperature, it is to avoid together with lower support 1 freezes with upper machine body 2.Defrosting adds heat pipe 4 and can be selected for electrothermal tube or heating wire, it is possible to select steam heating；Can be selectively mounted on lower support 1 or upper machine body 2, it is possible to all install on lower support 1 or upper machine body 2.
Obviously, above-described embodiment of the present utility model is merely to illustrate that this utility model example, and not restriction to embodiment of the present utility model.For those of ordinary skill in the field, change or the variation of other multi-forms can also be made on the basis of the above description.Here without also all of embodiment being given poor example.And these belong to obvious change that connotation of the present utility model amplified out or variation still falls within protection domain of the present utility model.
