[Problem to be solved by the invention]

The first conventional example of the hardening treatment apparatus has a configuration in which the popsicle (15) is passed through the quick-freezing hood (16) and nitrogen gas is sprayed during the passage. ), and the freezing effect is extremely small. In addition, in the second conventional example, popsicles (15
) is intermittently immersed, and in order to maintain production efficiency at a certain level, the current situation is that the immersion time per soak cannot be long. As a result, the coating material is pulled up without being sufficiently frozen, and even if this process is repeated, the coating material often peels off, resulting in defective products. Since only a thin coating can be applied, the freezing effect is not as strong as in the first conventional example. Extremely small. Therefore, according to the first and second conventional examples, if a thick coating layer of chocolate or the like is formed on the surface of the popsicle (15), this coating layer will not freeze.
5) It is difficult to form a thick coating layer such as granules, jelly, sherhet, pulp, etc. on the surface;
It was only possible to manufacture popsicles that had approximately the same shape as the molded water tube, and it was not possible to diversify and upgrade the product. Although it is possible to lengthen the soaking time, doing so will significantly reduce production efficiency.
There are practical problems.

The present invention was proposed in view of the above-mentioned problems, and an object of the present invention is to provide a surface hardening treatment device for the manufacturing process of frozen confectionery, etc., which can diversify and upgrade products without reducing production efficiency.

The mounted holding bar is driven by the transport means,
After transferring the frozen confectionery, etc. suspended from the holding bar to the other end of the transfer means while immersed in the quick-freezing solution in the quick-freezing tank, the frozen dessert is lifted by the other lifting means at the quick-freezing end position and transferred to the transfer means. It is designed to be temporarily held.

comes into contact with the support rail (76) (76) and returns to its original state. Thereafter, by repeating the above operation, the holding bar (25) located at the rapid freezing start position (g) is moved by a fixed pinch toward the rapid freezing end position (h).

In the above example, one coating step and one quick freezing step were provided, but by alternately providing a plurality of coating steps and quick freezing steps, it is possible to form multiple coating layers on the popsicle. can. Also,
It is clear that the present invention can be applied not only to popsicles but also to other frozen desserts and frozen foods.

〔Effect of the invention〕

According to the present invention, since the coated frozen confectionery can be transferred while immersed in the freezing solution, the surface hardening treatment of the frozen confectionery etc. can be carried out continuously and over a long period of time without reducing production efficiency. This makes it possible to rapidly freeze a thick coating layer formed on the surface of frozen confectionery, etc., with high efficiency and reliably. Therefore, it is possible to thickly apply various coatings such as granular, jelly-like, sherbento-like, pulpy, sleet-like, and granular chocolate to the surface of frozen desserts, etc., to obtain voluminous products with high efficiency. , it is possible to diversify and upgrade products.
