Description

Technical Field

[0001] This utility model relates to the field of dough proofing technology, specifically to a temperature and humidity controller for dough proofing. Background Technology

[0002] Proofing refers to the process by which dough, after initial fermentation, is allowed to relax and expand further under static conditions and appropriate temperature and humidity. The purpose of proofing is to allow the yeast in the dough to continue fermenting and producing carbon dioxide gas, thereby making the dough soft and elastic, preparing it for subsequent shaping and baking.

[0003] In the process of mass bread production, in order to increase the speed of dough proofing, it is usually placed inside a proofing box or fermentation chamber. A temperature and humidity controller is a control device specifically used to control the temperature heating rods or humidifiers inside the proofing box or fermentation chamber to adjust the temperature heating rods or humidity, so as to provide a suitable environment for the dough to proof. Such a control device used to control the heating rods and humidifiers can be called a temperature and humidity controller for dough proofing.

[0004] However, when the heating rod used to control the temperature is turned off by the temperature and humidity controller, the heating rod itself still has some residual heat. This residual heat will continue to heat the internal environment of the proofing box or fermentation chamber, which may affect the temperature control effect of the equipment. Therefore, it does not meet the existing needs. To address this, we have proposed a temperature and humidity controller for dough proofing. Utility Model Content

[0005] The purpose of this invention is to provide a temperature and humidity controller for dough proofing, in order to solve the problems mentioned in the background art, such as the residual heat in the heating rod after it is turned off by the temperature and humidity controller, which may affect the temperature control effect of the equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a temperature and humidity controller for dough proofing, comprising a proofing box shell, a smart temperature and humidity controller body fixedly installed on one side of the rear end face of the proofing box shell, a heating proofing rod connected to the front end face of the smart temperature and humidity controller body, a metal shell fixed to the outer surface of the smart temperature and humidity controller body on the outer side of the heating proofing rod, a stepper motor fixedly installed on one side inside the metal shell, the output shaft of the stepper motor connected to a transmission shaft via a coupling, a first bevel gear fixedly sleeved on the outer surface of the transmission shaft, a second bevel gear meshing on both sides of the outer surface of the first bevel gear, a gear shaft connected to the shaft of the second bevel gear, a threaded rod fixedly connected to the upper end face of the first gear shaft and the lower end face of the second gear shaft from top to bottom, an internal threaded sleeve installed on one side of the outer surface of the threaded rod via a threaded structure, a sealing plate fixedly connected to the rear end face of the internal threaded sleeve, and a storage groove provided on the side of the sealing plate facing the heating proofing rod;

[0007] The sealing plate has a cooling water collection tank inside, and the cooling water collection tank contains cooling water.

[0008] Preferably, a guide rod is provided behind the sealing plate and located inside the metal outer shell. A guide sleeve is movably fitted on one side of the outer surface of the guide rod, and the surface of the guide sleeve facing the sealing plate is fixed to the sealing plate.

[0009] Preferably, the shape of the inner wall of the storage slot corresponds to the shape of the outer surface of the heated proofing stick, and the two storage slots are located above and below the heated proofing stick, respectively.

[0010] Preferably, the top end of the first threaded rod and the bottom end of the second threaded rod are both located inside the metal housing, and the threaded rods located inside the metal housing are connected to the metal housing by roller bearings.

[0011] Preferably, the outer side of the metal casing is provided with a mounting groove located on the outer surface of the proofing box casing, and the metal casing is fixed to the inside of the mounting groove by screws.

[0012] Preferably, the outer side of the rear end of the heated proofing stick is connected to a heating tube fixing base by a threaded structure, and the heating tube fixing base is fixed to the main body of the intelligent temperature and humidity controller by screws;

[0013] The heating element mounting base is provided with an electrical connection wire on its inner side, and the main body of the intelligent temperature and humidity controller is connected to the heating and proofing rod through the electrical connection wire.

[0014] Preferably, the stepper motor is provided with a protective cover plate located on the outer surface of the metal casing, and the metal casing and the protective cover plate are fixed together by screws.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model features a heating proofing rod with a sealing plate at both the top and bottom for temperature control. When the heating proofing rod is turned off, a stepper motor automatically starts, pushing the two sealing plates towards the heating proofing rod until the top and bottom ends of the heating proofing rod enter the receiving grooves located on the outer surface of the two sealing plates. Once the heating proofing rod is fully inside the two sealing plates, the cooling water inside the sealing plates absorbs the heat remaining on the outer surface of the heating proofing rod, thus preventing the residual heat on the heating proofing rod from continuing to heat the internal environment of the proofing box or fermentation chamber. This technical solution improves the temperature control effect of the equipment.

[0017] 2. In this invention, when the upper and lower ends of the heating proofing rod are respectively inserted into the receiving grooves located on the outer surface of the two sealing plates, the entire heating proofing rod is also sealed by the two sealing plates. By using the two sealing plates to seal the heating proofing rod, it is possible to prevent the heat on the heating proofing rod from leaking into the proofing box or fermentation chamber during the process of absorbing the residual heat on the heating proofing rod by cooling water. The above technical solution further improves the temperature control effect of the equipment. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] The outer shell 1 (model LC-YH16C), the main body 2 (model OHR-WS10G), and the stepper motor 5 (model DM542) mentioned in this utility model can be obtained from the market or through private customization.

[0025] Please see Figures 1 to 4 This utility model provides an embodiment of a temperature and humidity controller for dough proofing, comprising a proofing box shell 1, a smart temperature and humidity controller body 2 fixedly installed on one side of the rear end face of the proofing box shell 1, a heating proofing rod 3 connected to the front end face of the smart temperature and humidity controller body 2, a metal shell 4 fixed to the outer surface of the smart temperature and humidity controller body 2 on the outer side of the heating proofing rod 3, a stepper motor 5 fixedly installed on one side inside the metal shell 4, and a transmission shaft 6 connected to the output shaft of the stepper motor 5 via a coupling. A first bevel gear 7 is fixedly sleeved on the outer surface of 6. A second bevel gear 8 meshes with both sides of the outer surface of the first bevel gear 7. A gear shaft 9 is connected to the shaft of the second bevel gear 8. A threaded rod 10 is fixedly connected to the upper end face of the first gear shaft 9 and the lower end face of the second gear shaft 9 from top to bottom. An internal threaded sleeve 11 is installed on one side of the outer surface of the threaded rod 10 through a threaded structure. A sealing plate 12 is fixedly connected to the rear end face of the internal threaded sleeve 11. A storage groove 13 is provided on the side of the sealing plate 12 facing the heating proofing rod 3.

[0026] The sealing plate 12 has a cooling water collection tank 14 inside, and the cooling water collection tank 14 contains cooling water 15.

[0027] The outer side of the rear end of the heated proofing stick 3 is connected to the heating tube fixing base by a threaded structure, and the heating tube fixing base is fixed to the main body 2 of the intelligent temperature and humidity controller by screws.

[0028] An electrical connection wire is provided on the inner side of the heating element fixing base, and the intelligent temperature and humidity controller body 2 is connected to the heating proofing rod 3 through the electrical connection wire. When the equipment needs to be used, the dough to be proofed is placed inside the proofing box, and then the intelligent temperature and humidity controller body 2 starts the heating proofing rod 3 located on the proofing box shell 1 to control the temperature inside the proofing box. The intelligent temperature and humidity controller body 2 can adjust the temperature of the heating proofing rod 3 in real time to ensure that the working power of the heating proofing rod 3 changes with the ambient temperature. In order to keep the ambient temperature inside the proofing box at a constant temperature, the intelligent temperature and humidity controller body 2 ensures that the heat generated by the heating proofing rod 3 and the heat dissipated are consistent to prevent the temperature inside the proofing box from fluctuating.

[0029] When it is no longer necessary to continue heating the inside of the proofing box, turn off the heating proofing rod 3 and start the stepper motor 5. The stepper motor 5 can drive the transmission shaft 6 connected to it to rotate. The rotating transmission shaft 6 can drive the first bevel gear 7 fixedly sleeved on the outer surface of the transmission shaft 6 and the two second bevel gears 8 meshing with the first bevel gear 7 to rotate. The rotating second bevel gears 8 can drive the gear shaft 9 connected to the axis of the second bevel gear 8 and the threaded rod 10 connected to the gear shaft 9 to continue to rotate.

[0030] A guide rod is located inside the metal housing 4 behind the sealing plate 12. A guide sleeve is movably fitted on one side of the outer surface of the guide rod, and the surface of the guide sleeve facing the sealing plate 12 is fixed to the sealing plate 12. Since the inner threaded sleeve 11, which is installed on the outer surface of the threaded rod 10 through a threaded structure, is fixed to the sealing plate 12, the inner threaded sleeve 11 cannot rotate on its own. When the threaded rod 10 rotates, it is threadedly connected to the inner threaded sleeve 11. However, the inner threaded sleeve 11, which cannot rotate on its own, will move up and down under the drive of the threaded structure. At this time, the two inner threaded sleeves 11 move inward simultaneously. As the inner threaded sleeves 11 move, the sealing plate 12, which is fixed to them, will also move inward together.

[0031] The shape of the inner wall of the storage groove 13 corresponds to the shape of the outer surface of the heating proofing rod 3, and the two storage grooves 13 are located above and below the heating proofing rod 3 respectively. As the sealing plate 12 moves, the upper and lower ends of the heating proofing rod 3 will gradually enter the interior of the storage grooves 13 located on the outer surface of the two sealing plates 12 respectively. When the two sealing plates 12 are merged together, the upper and lower ends of the heating proofing rod 3 will enter the interior of the storage grooves 13 located on the outer surface of the two sealing plates 12 respectively. When the heating proofing rod 3 is completely inside the two sealing plates 12, the cooling water 15 located inside the sealing plate 12 can absorb the heat remaining on the outer surface of the heating proofing rod 3, thereby preventing the heat remaining on the heating proofing rod 3 from continuing to heat the internal environment of the proofing box or fermentation chamber. The above technical solution improves the temperature control effect of the equipment.

[0032] When the upper and lower ends of the heating proofing rod 3 enter the storage grooves 13 located on the outer surface of the two sealing plates 12, the entire heating proofing rod 3 will be sealed by the two sealing plates 12. By sealing the heating proofing rod 3 with the two sealing plates 12, it is possible to prevent the heat on the heating proofing rod 3 from leaking into the proofing box or fermentation chamber during the process of absorbing the residual heat on the heating proofing rod 3 by the cooling water 15. The above technical solution further improves the temperature control effect of the equipment.

[0033] The stability of the sealing plate 12 as it moves up and down is ensured by a guide sleeve that is fixed between the sealing plate 12 and the rear end face of the sealing plate 12.

[0034] The top end of the first threaded rod 10 and the bottom end of the second threaded rod 10 are both located inside the metal housing 4, and the threaded rod 10 located inside the metal housing 4 is connected to the metal housing 4 by a roller bearing; the roller bearing structure between the metal housing 4 and the threaded rod 10 can ensure the stability of the rotating threaded rod 10.

[0035] The outer side of the metal casing 4 is provided with a mounting groove on the outer surface of the proofing box casing 1, and the metal casing 4 is fixed to the inside of the mounting groove by screws; the intelligent temperature and humidity controller body 2, the heating proofing rod 3 and the metal casing 4 can be fixedly installed through the mounting groove on the outer surface of the proofing box casing 1.

[0036] A protective cover plate is provided in front of the stepper motor 5 on the outer surface of the metal housing 4, and the metal housing 4 and the protective cover plate are fixed together by screws; the protective cover plate can protect the stepper motor 5, and when the stepper motor 5 fails, the protective cover plate can be removed to repair the stepper motor 5.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
