In the embodiment, the sweet potatoes in the first step to the seventh step are not peeled, so that the taste of the sweet potatoes is guaranteed, the nutrition cost of the sweet potatoes is locked through the outer skin, and the nutritional ingredient liquid diet of the sweet potatoes in the processing process is reduced.
In this example, the commercial standard is as follows:
sensory requirements
The ice baked sweet potato can be directly eaten, can be eaten after being unfrozen or can be eaten after being heated, and is convenient and quick on the basis of the traditional process, so that the production operation of the baked sweet potato is simple through the ice baked sweet potato. The product of the invention enters ice cream shops and supermarkets to be sold in refrigerators by utilizing the existing cold chain channel, is hermetically packaged, enters consumers and families, and can be directly eaten, heated by a microwave oven for use and soaked in boiling water for eating. By implementing the patent, an ice cream upgrading raw material is produced to form a unique Chinese iced product.
Example two
The difference between the second embodiment and the first embodiment is that, as shown in fig. 1 and fig. 2, in the fourth step, a natural cooling mode is generally adopted, and by adopting the natural cooling mode, the cooling efficiency of the roasted sweet potatoes is low, the time is long, and the cooling efficiency of the roasted sweet potatoes is greatly reduced.
To this end, a cooling device is used in step four to cool the roasted sweet potatoes, specifically: cooling arrangement includes cooler bin 11, and it has the feed inlet to open one side of cooler bin 11, and the last rotation of cooler bin 11 is connected with the door plant 19 that is used for sealing the cooling port, and the upper portion slope and the high right-hand member of left end of door plant 19 are low, and it has pressure release mouth 12 to open at the top of cooler bin 11, and pressure release mouth 12 internal fixation has and is used for dirt-proof filter screen 13.
In this embodiment, a supporting mechanism for supporting the roasted sweet potatoes is arranged in the cooling box 11, the supporting mechanism comprises a support 18 and a plurality of supporting plates 14 arranged on the support 18, a plurality of rollers are arranged at the bottom of the support 18, the supporting plates 14 are vertically and uniformly distributed along the support 18, a plurality of placing grooves 22 for placing the roasted sweet potatoes are formed in the supporting plates 14, and interlayers 23 are arranged in the placing grooves 22.
In this embodiment, the supporting plate 14 is provided with a plurality of cooling holes 21, and the plurality of cooling holes 21 are located on the outer periphery of the placing groove 22.
In this embodiment, a cooling channel is formed between adjacent supporting plates 14, a plurality of cooling valves 15 are fixed on the cooling box 11, the cooling valves 15 are communicated with the cooling channel, the cooling valves 15 are communicated with coolers 16, and the coolers 16 are communicated with air pumps 17.
The specific implementation process is as follows:
the roasted sweet potatoes are placed into the placing groove 22 in advance, and are separated from the supporting plate 14 through the partition layer 23, so that the roasted sweet potatoes are prevented from being stuck with the supporting plate 14 after being cooled.
The cooling box 11 is opened in the state of fig. 1, with the door panel 19 as a support platform for the operator to push the rack 18 and the support plate 14 into the cooling box 11.
When the supporting mechanism is located in the cooling box 11, the cooling valve 15 is communicated with the cooling channel, the air pump 17 and the cooler 16 are started, the air pump 17 sends air to the cooler 16, the air enters the cooling channel after being cooled by the cooler 16, and the cooling temperature of the cooler 16 in the embodiment is room temperature air. In the prior art, if gas is input into the cooling box 11 from the upper part, the temperature of the bottom is too high, so that the cooling efficiency of roasting sweet potatoes at the bottom is reduced, and if gas is input into the cooling box 11 from the lower part, the temperature of the upper part is too high, so that the cooling efficiency of examining sweet potatoes at the upper part is reduced.
Therefore, a plurality of coolers 16 are designed in the scheme, the cooler 16 at the lower part inputs cold air to the cooling channel at the lower part through the cooling valve 15, the cold air is used for cooling the baked sweet potatoes at the lower part, and the temperature of the air rises when the air rises, therefore, the cooler 16 at the middle part sends the cold air to the cooling channel at the middle part through the cooling valve 15, on one hand, the air rising from the lower part is cooled, on the other hand, the baked sweet potatoes at the middle part can be effectively and quickly cooled, and of course, the cooler 16 at the upper part also cools the rising air, thereby being beneficial to cooling the baked sweet potatoes at the upper part. The cooled gas is discharged through the pressure relief port 12, and the internal pressure in the cooling box 11 is reduced.
In this embodiment, because cooling hole 21 is along standing groove 22's circumference equipartition, then carry out circumference cooling to roast sweet potato, improve the cooling area for roast sweet potato cools off fast, compares in concentrating to blow to roast sweet potato a position, and cooling efficiency is faster.
In the description herein, reference to the description of the terms "preferred embodiment," "one embodiment," "some embodiments," "an example," "a specific example" or "some examples" or the like means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the invention. In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
While embodiments of the invention have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
