Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of drying equipment, and particularly relates to a scraping device, and especially relates to a drying equipment and a working method thereof. BACKGROUND

[0002] In the atomization and granulation process, the fish collagen peptide solution needs to be dried. In the process of drying the fish collagen peptide solution by using a double-cone vacuum dryer, the inside of the bin is first pumped to a set vacuum degree to reduce the boiling point of water, thereby accelerating the evaporation of water. At the same time, a heating medium (such as steam, heat-conducting oil, etc.) heats the bin through a heating jacket to increase the temperature of the material and further promote the evaporation of water.

[0003] The water in the fish collagen peptide solution is precipitated from the solution. Since the fish collagen peptide solution is an amphiphilic molecule (having both hydrophilic and hydrophobic groups), the fish collagen peptide solution spontaneously migrates to the gas-liquid interface to reduce the surface tension of the solution. When the fish collagen peptide solution is disturbed or internal gas is precipitated, these peptide molecules will quickly wrap the gas to form a stable foam layer. In the low-speed period of the double-cone vacuum dryer (the early stage of drying), the fish collagen peptide solution has low viscosity. In this process, even if the double cone is rotating, the fish collagen peptide solution is still stably at the bottom of the double cone and is not easy to be lifted with the double cone. At this time, the foam layer formed by the water precipitated from the fish collagen peptide solution is stable on the surface of the fish collagen peptide solution and gradually expands, and it is difficult to be broken due to the movement of the double cone. If the bubble layer expands to the limit and breaks, the gas in the bubble overflows, causing a large fluctuation in the vacuum degree inside the double cone, causing the boiling point of water to rise again. This reciprocating prolongs the low-speed period of the double-cone vacuum dryer, reducing the overall drying efficiency.

[0004] Therefore, there is an urgent need to develop a new drying equipment and a working method thereof to solve the technical problem that the traditional double-cone vacuum dryer is in the low-speed period and the bubble layer produced by the fish collagen peptide solution expands to the limit and breaks, causing a fluctuation in the vacuum degree inside the double cone in the preparation process of fish collagen peptide.

[0029] It was found through research that if the pumping speed is too fast at the beginning of high vacuum, the solvent in the fish collagen peptide solution (especially ethanol with a low boiling point) will boil violently, and foam will be generated on the surface of the fish collagen peptide solution. When the foam breaks, the semi-dry fish collagen peptide solution will be sprayed out, causing material spraying, and a large amount of steam will be released, causing fluctuations in the vacuum degree. If low-speed pumping is used, slow warming and drying will result in too long crystallization time of the fish collagen peptide solution, which will further cause grain coarsening, affecting the subsequent processing performance. The centrifugal force generated by the rotation of the double-cone dryer is not enough to break the foam film.

[0030] Based on the above research, the dry equipment and the working method thereof are provided, which actively breaks the small foam generated in the process of drying the fish collagen peptide solution, and can overcome the problem that the foam generated in the process of drying the fish collagen peptide solution expands to the limit and is broken, resulting in fluctuation of vacuum degree.

[0031] The above-mentioned defects are the results of the inventors after practice and careful research, and therefore, the discovery process of the above-mentioned problems and the solutions provided by the present disclosure to the above-mentioned problems should be the contributions of the inventors to the present disclosure.

[0032] It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0033] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the case of no conflict, the embodiments described below and the features in the embodiments can be combined with each other.

[0034] As shown in Figures 1 to 3 At least one embodiment provides a drying equipment, which comprises a bin 1, a ventilation mechanism 2, a drying mechanism 3, a first power mechanism 4, a foam breaking mechanism 5 and a second power mechanism 6; wherein the ventilation mechanism 2 is in communication with an inner cavity 11 of the bin 1, the drying mechanism 3 is in communication with an outer cavity 12 of the bin 1, and the first power mechanism 4 is connected with the bin 1; the foam breaking mechanism 5 is located in the inner cavity 11, the foam breaking mechanism 5 is connected with the ventilation mechanism 2, and the second power mechanism 6 is movably connected with the foam breaking mechanism 5; when fish collagen peptide solution is put into the inner cavity 11, the ventilation mechanism 2 evacuates the inner cavity 11 and fills hot nitrogen into the inner cavity 11, the drying mechanism 3 circulates to pump a heat preservation source into the outer cavity 12, and the first power mechanism 4 drives the bin 1 to rotate to dry the fish collagen peptide solution in the inner cavity 11; the second power mechanism 6 drives a cutter 573 in the foam breaking mechanism 5 to rotate around a vertical shaft to break the foam generated by the fish collagen peptide solution deposited in the inner cavity 11; and the second power mechanism 6 drives the cutter 573 in the foam breaking mechanism 5 to rotate around a horizontal shaft to separate the fish collagen peptide solution on the cutter 573.

[0035] In at least one embodiment, by setting the foam breaking mechanism 5 in the silo 1 to actively break the small foam generated during the drying of the fish collagen peptide solution, the problem of the foam generated during the drying of the fish collagen peptide solution expanding to the limit of breaking and causing fluctuations in the vacuum degree can be overcome. At the same time, the foam breaking mechanism 5 rotates while rotating, the fish collagen peptide solution adhered to the cutter 573 is thrown away by the centrifugal force in two different directions, avoiding the local high temperature on the surface of the cutter 573 causing the fish collagen peptide crystals adhered to it, and the ventilation mechanism 2 supplements nitrogen in the inner cavity 11, ensuring that the oxygen concentration in the inner cavity 11 is maintained at a low level even if oxygen is generated by the decomposition of the fish collagen peptide solution.

[0036] In at least one embodiment, referring to Figure 2 , the ventilation mechanism 2 includes: an air extraction pipeline 21 and a vacuum pump; the air extraction pipeline 21 is in communication with the inner cavity 11; the air extraction pipeline 21 is connected with the vacuum pump to extract vacuum in the inner cavity 11.

[0037] Specifically, the air extraction pipeline 21 cooperates with the vacuum pump to extract vacuum in the inner cavity 11, so that the inner cavity 11 forms a vacuum negative pressure state, reduces the boiling point of the solvent in the wet material to precipitate the solvent, and dries the fish collagen peptide solution by combining the two aspects of reducing the boiling point to strengthen evaporation and updating the heat transfer surface.

[0038] In at least one embodiment, referring to Figure 2 , the ventilation mechanism 2 includes: an air extraction pipeline 21 and a vacuum pump; the air extraction pipeline 21 is in communication with the inner cavity 11; the air extraction pipeline 21 is connected with the vacuum pump to extract vacuum in the inner cavity 11.

[0039] Specifically, the air extraction pipeline 21 and the air charging pipeline 22 are both hard pipelines, and the air charging pipeline 22 is inside the air extraction pipeline 21.

[0040] Specifically, the foam breaking mechanism 5 breaks the foam by mechanical breaking during rotation, reduces the risk of material spraying, and at the same time, the air charging pipeline 22 cooperates with the nitrogen pump to supplement nitrogen in the inner cavity 11. When the foam naturally bursts, the oxygen generated by the decomposition of the fish collagen peptide solution can make the oxygen concentration in the inner cavity 11 suddenly rise to 18% (combustion limit), and the cutter 573 breaks and maintains the oxygen concentration <0.5% under continuous nitrogen charging, to improve the safety of the operation.

[0041] Specifically, hot nitrogen is pumped into the inner cavity 11 to control the vacuum degree of the inner cavity 11 by controlling the air intake, and the wet material is dried with the help of hot nitrogen; In the later stage of drying the fish collagen peptide solution, the evaporation amount of the material is small, and the pressure difference between the inside and outside of the material pile is very small, which significantly reduces the drying efficiency and significantly prolongs the drying time. Therefore, hot nitrogen is pumped into the inner cavity in the later stage of drying to further promote drying.

[0050] Specifically, the support box 51 is fixed, and the fixed rod 55 and the third bevel gear 56 are also fixed, while the connecting rod 572 rotates with the rotating sleeve 54 under the action force of the rotating sleeve 54, and the fourth bevel gear 571 rotates relative to the third bevel gear 56, thereby the fourth bevel gear 571 drives the connecting rod 572 and the cutter 573 to rotate around the horizontal shaft, i.e. the cutter 573 rotates.

[0051] Specifically, the cutter 573 is located 15±3 cm above the surface of the wet material.

[0059] In at least one embodiment, referring to Figure 1 , a jacket 13 is arranged in the hopper 1 to divide the inner cavity 11 and the outer cavity 12 in the hopper 1.
