Description

Fruit juice thawing apparatus Technical Field The invention relates to the technical field of fruit juice production devices, in particular to a fruit juice thawing device. Background In the fruit juice production process, frozen fruit juice, fruit puree or jam is required to be subjected to thawing treatment before use, so that the frozen fruit juice, fruit puree or jam is recovered to be in a flowable liquid state from a frozen state, so that subsequent blending, sterilization and filling are realized, the process generally depends on external heat transfer to the inside of materials, ice crystals are gradually thawed, and meanwhile, the heat exchange area is increased by combining a mechanical crushing means, so that the thawing efficiency is improved. The existing frozen juice thawing device generally adopts the working mode that large blocks of fruit materials in a deep cooling state are directly put into a crushing cavity, hot water is introduced into the crushing cavity through a jacket on the outer wall of the cavity for heating while crushing, crushing and thawing are synchronously completed in the same equipment, and the working mode that crushing is carried out while heating has obvious defects in practical application, because the materials are still hard frozen blocks, the hard frozen blocks are directly subjected to high-strength cutting, so that the equipment load is large, the cutter is worn fast, the energy consumption is high, meanwhile, the crushing cutter is difficult to process the hard frozen blocks into tiny and uniform particles, the material granularity difference is large, the heat exchange area is insufficient, the heat can only be conducted slowly by the cavity wall, the outer layer materials are excessively heated, unmelted frozen cores still exist in the inner part, fragrance components in juice are volatilized after overheating, the thermosensitive nutrient substances are degraded, the color is changed, and the flavor and the quality of the final product are influenced. Disclosure of Invention Aiming at the defects in the prior art, the invention provides a fruit juice thawing device which solves the problems that the thawing uniformity of the existing device is poor and the flavor and quality of the final product are affected. According to the embodiment of the invention, the fruit juice thawing device comprises a frame, wherein the frame is provided with a pre-thawing mechanism, an ice crushing mechanism and a heating mechanism in sequence from top to bottom; The pre-defrosting mechanism is fixed at the uppermost part of the frame and comprises a defrosting box, an opening is formed in one side of the defrosting box, a movable blocking cover is arranged at the opening, a defrosting frame is arranged in the defrosting box in a sliding mode, an air inlet part is arranged at the top of the defrosting box, an air source is externally connected with the air inlet part, and an air outlet part is arranged at the bottom of the defrosting box; the ice crushing mechanism comprises an ice crushing refrigerator, the top of the ice crushing refrigerator is communicated with the thawing box, an ice crushing roller is rotatably arranged in the ice crushing box, and a first motor capable of driving the ice crushing roller to rotate is fixedly arranged on one side of the ice crushing box; The heating mechanism comprises a heating tank, the heating tank is fixed at the bottom of the frame and is communicated with the bottom of the ice crushing box, a heating jacket is fixedly arranged outside the heating tank, a water inlet pipe and a water outlet pipe are arranged in communication with the heating jacket, a hot water source is externally connected with the water inlet pipe, a stirring rod is rotationally arranged in the heating tank, and a second motor capable of driving the stirring rod to rotate is arranged at the top of the heating tank. When the ice-breaking device is used, frozen fruit blocks are placed on a thawing frame in a thawing box, a movable blocking cover is closed, cold air is conveyed into the box through an external air source by an air inlet part, the cold air passes through the thawing frame from top to bottom and is discharged from an air outlet part, the surface of the frozen fruit blocks is gradually softened, the cross section size of the frozen blocks is gradually reduced along with the thawing of surface ice crystals, when the size of the frozen blocks is smaller than the feeding hole of a baffle plate at the bottom of the thawing frame, the frozen blocks automatically fall into a refrigerator below under the action of gravity, a ice-breaking roller rotates under the driving of a first motor, the pre-thawed frozen fruit blocks are gradually broken into tiny and uniform ice-sand particles, the ice-sand particles fall into a heating tank, the heating jacket is heated by hot water introduced through a water inlet pipe, and a stirring rod is driven to rotate by a second
