Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and more specifically, to a drying equipment for preservative raw materials. Background Technology

[0002] Preservative raw materials are not single substances, but are categorized according to their application (such as food, cosmetics, and industry), with their core function being to inhibit microbial growth. In the food industry, potassium sorbate, sodium benzoate, and sodium dehydroacetate are the most widely used types. In the industrial industry, formaldehyde releasers (such as DMDM ​​hydantoin) and isothiazolinones are commonly used in coatings and adhesives.

[0003] Most preservative raw materials are prone to absorbing moisture. A humid environment can cause them to clump, mold, or even become contaminated by microorganisms, thus losing their preservative effect. This also makes them difficult to crush and mix, reducing storage time. Therefore, a preservative raw material drying device is provided. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a preservative raw material drying device, which aims to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a preservative raw material drying device, including a pad, on which a drying component is provided;

[0006] The drying assembly includes a protective cylinder disposed on top of a pad, an inner liner disposed in the middle of the protective cylinder, an electric heating wire disposed between the protective cylinder and the inner liner, a turntable rotatably connected to the bottom of the inner cavity of the inner liner, and a mixing belt mounted on the top of the turntable by bolts.

[0007] The bottom of the turntable is provided with a frustum column, and several blades are provided on the outer side of the frustum column.

[0008] Optionally, in one possible implementation, the surface of the turntable is provided with a plurality of sieve holes, and the top of the truncated column is detachably connected to the turntable by bolts.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This embodiment discloses a preservative raw material drying device, which aims to solve the problems in the prior art where preservative raw materials are prone to moisture absorption, clumping, and mold growth, making them difficult to crush and mix, shortening storage time, and resulting in uneven heating and low drying efficiency during the drying process.

[0021] The overall structure of this preservative raw material drying equipment is shown in the attached figure. Figure 1 As shown, its core components include a pad 1, a drying assembly, a temporary storage and discharge assembly, and a drive assembly. The specific structure and connection relationship of each component are as follows:

[0022] The base plate 1, as the basic support component of the entire equipment, is made of stainless steel and has good load-bearing capacity and corrosion resistance. It can ensure that the equipment remains stable during long-term use and prevent the components from shifting due to vibration.

[0023] The drying assembly is the core component for drying preservative raw materials, and its structure is shown in the attached figure. Figure 2 Appendix Figure 3 As shown:

[0024] The protective cylinder 2 is fixed to the top of the pad 1 by welding. It has a cylindrical structure and its function is to protect the internal components, prevent external impurities from entering, and reduce heat loss.

[0025] The inner liner 3 is coaxially positioned in the middle of the protective cylinder 2. The inner liner 3 is made of high-temperature resistant ceramic, which has good thermal conductivity and stability, and can avoid chemical reaction with the preservative raw materials.

[0026] An annular cavity is formed between the protective cylinder 2 and the inner liner cylinder 3. An electric heating wire 4 is evenly wound in the cavity. The electric heating wire 4 is made of nickel-chromium alloy and can generate stable heat after being powered by an external power source. The heat is conducted to the inner cavity through the inner liner cylinder 3, providing a heat source for drying the preservative raw materials.

[0027] The turntable 5 is located at the bottom of the inner cavity of the inner liner 3 and is rotatably connected to the bottom of the inner liner 3 via ball bearings, allowing for flexible rotation.

[0028] A mixing belt 6 is evenly installed on the top of the turntable 5 via bolts. The mixing belt 6 has a spiral structure and is made of food-grade stainless steel for food preservative raw materials or industrial-grade corrosion-resistant stainless steel for industrial preservative raw materials. When the turntable 5 rotates, the mixing belt 6 can stir and agitate the preservative raw materials falling on the turntable 5, ensuring that the raw materials are evenly exposed to heat and avoiding local overheating or incomplete drying.

[0029] As attached Figure 3 Appendix Figure 4 As shown, the surface of the turntable 5 is perforated with several sieve holes 7, the diameter of which is set to 0.5-2mm according to the particle size of the preservative raw material. During the drying process, raw materials that have reached the drying requirements and whose particle size meets the standard can fall through the sieve holes 7 to the collection component below, while raw materials that are not completely dried and have clumped remain on the turntable 5 and are further stirred and dried by the mixing belt 6 until they meet the requirements and then fall through the sieve holes 7, thus achieving simultaneous drying and screening.

[0030] As attached Figure 3 Appendix Figure 4 As shown, a frustum column 8 is coaxially mounted on the bottom of the turntable 5. The top of the frustum column 8 is detachably connected to the turntable 5 by bolts, facilitating future maintenance and replacement. Several blades 9 are evenly welded to the outer side of the frustum column 8 along its generatrix. The blades 9 have an arc-shaped structure. When the turntable 5 rotates, the frustum column 8 rotates synchronously. During the rotation of the blades 9, an upward airflow is formed at the bottom of the inner liner 3. This airflow serves two purposes: firstly, it provides secondary drying for the falling raw material particles; secondly, it prevents the raw material particles from clogging the screen holes 7 during their descent, ensuring a smooth screening process.

[0031] As attached Figure 1 Appendix Figure 2 As shown, a temporary storage box 10 is installed on the outer side of the frustum column 8. The temporary storage box 10 is bolted to the bottom of the pad 1, and its top is open to fully receive the dried raw material falling from the sieve holes 7. A tilting valve 11 is installed on the lower outer side of the temporary storage box 10, which is connected to the inner cavity of the temporary storage box 10. The valve can be manually or electrically controlled according to actual needs. When the dried raw material collected in the temporary storage box 10 reaches a certain amount, the discharge valve 11 can be opened to discharge the raw material, facilitating subsequent packaging and storage.

[0032] As attached Figure 1 Appendix Figure 2As shown, a cover plate 12 is detachably connected to the top of the protective cylinder 2 via bolts. The cover plate 12 is made of stainless steel and can seal the top of the protective cylinder 2 to reduce heat loss. A motor 13 is bolted to the top of the cover plate 12. The motor 13 is a stepper motor with adjustable speed. Its output end passes through the cover plate 12 and extends to the top of the turntable 5. It is fixedly connected to the turntable 5 via a coupling, providing power for the rotation of the turntable 5. A feed pipe 14 is provided on one side of the motor 13. The bottom end of the feed pipe 14 passes through the cover plate 12 and extends to the bottom of the cover plate 12, and the bottom end of the feed pipe 14 is located above the inner liner cylinder 3. The preservative raw material to be dried can be added into the inner cavity of the inner liner cylinder 3 through the feed pipe 14 and fall onto the turntable 5 for drying.

[0033] The specific working principle is as follows: First, the power supply to the electric heating wire 4 is turned on. The electric heating wire 4 generates heat, which is conducted to its inner cavity through the inner liner 3. At the same time, the motor 13 is started, and the motor 13 drives the turntable 5 to rotate. The turntable 5 drives the mixing belt 6, the frustum column 8, and the blades 9 to rotate synchronously. Furthermore, during use, a temperature sensor can be installed on the inner wall of the inner liner 3 to monitor the temperature of the inner cavity in real time. When the temperature reaches the preset drying temperature, which is based on the characteristics of the preservative raw materials, the preset temperature range is 50-80℃. For example, the preset drying temperature for potassium sorbate in the food industry is 60℃, and the preset drying temperature for isothiazolinones in the industrial industry is 75℃, then the next step of operation is performed.

[0034] The preservative raw material to be dried is slowly added into the inner cavity of the inner liner cylinder 3 through the feed pipe 14, and the raw material falls onto the rotating turntable 5.

[0035] The raw materials falling on the turntable 5 are constantly turned over by the mixing belt 6, and are evenly contacted by the heat conducted by the inner liner cylinder 3. The moisture in the raw materials gradually evaporates, thus achieving drying.

[0036] During the drying process, the blades 9 rotate with the frustum 8 to form an upward airflow, which on the one hand assists in drying the raw materials, and on the other hand prevents the raw materials from clogging the screen holes 7.

[0037] When the raw materials are dried to the required moisture content (e.g., ≤0.5% for food preservatives, ≤1% for industrial applications) and the particle size meets the standard, they can fall into the temporary storage box 10 through the sieve holes 7 on the turntable 5. Raw materials that do not meet the standard, are clumped, or are not thoroughly dried will continue to be stirred and dried on the turntable 5 by the mixing belt 6 until they meet the standard and then fall.

[0038] When the amount of dried raw material collected in the temporary storage box 10 reaches the preset amount, turn off the electric heating wire 4 and the motor 13, open the inclined material valve 11, discharge the dried raw material and carry out subsequent packaging and storage.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
