Description

Technical Field

[0001] The present invention relates to the field of pasta processing equipment, and particularly to a refrigerated proofing and heating integrated machine. Background Art

[0002] Currently, the breakfast industry generally adopts a segmented processing mode of "central kitchen pre-fermentation of cooked dough + terminal steam reheating". Its core defect lies in the disconnection of the biochemical reaction chain caused by the fragmentation of equipment functions. After the raw dough is steamed and quick-frozen in the central kitchen, the yeast activity has completely disappeared, and the terminal store can only rely on a single steam cabinet to conduct high-temperature reheating of the frozen cooked dough. This process not only fails to restart the natural metabolic path of the dough (such as the synthesis of esters and the reconstruction of the gluten network), but also due to problems such as ice crystals damaging the gluten and the secondary aging of starch, it leads to a hard texture and flavor loss of the finished product. More critically, the existing equipment cannot achieve continuous control of "thawing - proofing - heating" at the terminal. If the store attempts to make it on-site, it needs to stack independent equipment, but the disconnection of temperature and humidity parameters and the environmental exposure caused by manual transfer further lead to texture abnormalities such as epidermal cracking and uneven fermentation.

[0003] The upgrading of market demand is forcing the innovation of technical paths. The contradiction between consumers' demands for "freshly made on-site" pasta foods (such as buns and steamed buns) and the store's meal preparation efficiency exposes the underlying logic of the traditional process of "efficiency first, quality compromised" - although pre-cooled and frozen cooked dough can be quickly reheated, it loses the unique fermentation aroma of freshly made pasta foods.

The greenhouse balanced steam is supplied to the processing chamber through the air permeable window.

[0006] In a possible implementation manner, the heating device conditions the steam generated by the steam generating device into greenhouse balanced steam with a temperature of 35 - 38 °C and a humidity of 75 - 85 RH%.

[0020] In order to make the objectives, technical solutions, and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings.

[0021] In the present application, orientation terms such as "upper" and "lower" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, which are used for relative description and clarification, and they can change accordingly with the change of the orientation of the components placed in the accompanying drawings.

[0022] The present invention provides a refrigerated proofing and heating integrated machine. As shown in the accompanying Figures 1 to 4 drawings, the integrated machine includes a chassis 1, a heating device 2, a steam generating device 3, and a refrigeration device. The interior of the chassis 1 is separated by a partition 11 to form a processing chamber 102 and an equipment chamber 101. The processing chamber 102 is used to place the raw dough food to be processed. Both the heating device 2 and the steam generating device 3 are arranged in the equipment chamber 101. The partition 11 is provided with an openable and closable air permeable window 103, so that the equipment chamber 101 and the processing chamber 102 are in communication. Preferably, the air permeable window 103 is provided with a louvered partition 11, and the opening and closing angle of the louvered partition 11 controls the opening and closing state of the air permeable window 103. The setting of this partition 11 physically isolates the equipment chamber 101 and the processing chamber 102 to ensure the stability of the temperature zone. Further, both the equipment chamber 101 and the processing chamber 102 are configured with door panels 12 to achieve the sealing and opening of each chamber.

[0023] Refer to the accompanying Figure 5, preferably, a plurality of sliding grooves 13 are vertically arranged on both sides in the processing chamber 102, and the sliding grooves 13 on both sides in the processing chamber 102 correspond to each other in the height direction, and the corresponding two sliding grooves 13 support a tray 5. After the green dough to be made is placed on the tray 5, both sides of the tray 5 are respectively inserted into the corresponding two sliding grooves 13, and then the tray 5 is pushed into the processing chamber 102, so that the green dough can be stacked in multiple layers from top to bottom in the processing chamber 102. Further, rollers 51 can be arranged on both sides of the tray 5, and the rollers 51 are adaptively inserted into the sliding grooves 13 to make the action of pushing the tray 5 into the processing chamber 102 smoother.

[0024] The heating device 2 is configured to generate hot air and output the hot air into the processing chamber 102 through the air permeable window 103 to heat the pasta food. Specifically, as shown in the appendix Figure 6 shown, the heating device 2 includes a frame body 21 and a heating unit 22. The heating unit 22 is fixed in the frame body 21, and the frame body 21 is fixed to the side of the partition 11. The heating unit 22 can be an electric heating tube for converting electrical energy into heat energy. Further, referring to the appendix Figure 3 again, a heat conducting fan 6 is fixed on the frame body 21, and the air outlet direction of the heat conducting fan 6 faces the air permeable window 103. When the working mode of the all-in-one machine of the present invention is adjusted to the heating mode, the air permeable window 103 of the partition 11 is opened, the heating unit 22 of the heating device 2 generates hot air, and the heat conducting fan 6 supplies the hot air to the processing chamber 102 through the air permeable window 103.

[0025] The steam generating device 3 is configured to generate steam, and the steam is supplied into the processing chamber 102 through the air permeable window 103 to realize the proofing of the green dough. Specifically, as shown in the appendix Figure 3 and 4 shown, the steam generating device 3 is arranged under the heating device 2. The steam generating device 3 includes a water tank 31 with air holes distributed above the water tank 31, and a heating unit 22 for heating is arranged in the water tank 31. When the working mode of the all-in-one machine of the present invention is adjusted to the proofing mode, the air permeable window 103 is opened. When the heating unit 22 in the water tank 31 heats the water in the water tank 31, the water is heated to form steam, which rises through the air holes, is guided by the heat conducting fan 6 to pass through the heating device 2, and then is directionally supplied to the processing chamber 102 through the air permeable window 103. In this process, the temperature and humidity of the steam are precisely controlled through the heat exchange process with the heating device 2, that is, the temperature of the steam may drop and the humidity may be too high during the rising process of the steam. Through the secondary heating modulation of the heating device 2, a greenhouse balanced steam suitable for the proofing process of the green dough is formed. For example, the heating unit 22 of the heating device 2 modulates the steam fired by the water tank 31 into a greenhouse balanced steam with a temperature of 35-38 °C and a humidity of 75-85%RH, so that the air input into the processing chamber 102 meets the temperature conditions and humidity conditions for the proofing of pasta food, activates the yeast activity and reorganizes the gluten structure, and Maintain the epidermal water content by balancing the steam in the greenhouse, and synchronously achieve core layer fermentation and epidermal flexibility. Make the final heated pasta food have a taste close to that of freshly made handmade pasta.

[0026] The refrigeration device is configured to generate cold air. Figure 4 As shown, the refrigeration device includes an evaporator 41, a compressor 42 and a condenser 43. The evaporator 41 is fixed in the equipment room 101, and the compressor 42 and the condenser 43 are fixed to the top of the chassis 1. The heat-conducting fan 6 is fixed to the top of the heating device 2 and the evaporator 41, so that the heat-conducting fan 6 can supply the cold air emitted by the evaporator 41 to the processing room 102 through the air-permeable window 103. When the working mode of the all-in-one machine of the present invention is adjusted to the refrigeration mode, the refrigeration device supplies cold air to the refrigeration room 103 to realize the refrigerated storage of pasta food, so as to inhibit the microbial activity of the raw pasta and ensure that the raw pasta remains in a dormant state after cold chain transportation.

[0027] In addition, the all-in-one machine of the present invention can also be configured with a control system, which can be a PLC controller for controlling the opening and closing of the heating device, steam generating device, refrigeration device and heat-conducting fan according to the above working mode, so as to seamlessly connect the temperature control requirements of different processing stages. Specifically in commercial scenarios, after the quick-frozen raw dough pasta is delivered to the terminal through the cold chain and placed in the processing chamber 102 in the all-in-one machine of the present invention, the thawing time, the proofing time and the heating time of the raw dough pasta are calculated according to the steaming time point required in the morning, so as to set the corresponding time on the control system. That is, the operator only needs to set the next day's meal time on the panel configured by the control system, and the system automatically plans the whole process: first, maintain the refrigeration mode to ensure that the dough pasta is in a low-temperature dormant state of preservation, and release the refrigeration mode after the preset time to allow the raw dough pasta to thaw naturally. The thawing time can be flexibly set according to the needs to adapt to different environmental conditions (normally 2-3 hours, which can be set according to the temperature of each place). After the thawing stage is over, the control system will automatically switch to the proofing mode, and finally accurately execute the heating mode. The entire process does not require human intervention, which not only ensures work efficiency during the early morning meal preparation period, but also eliminates human operational errors through programmed control, ensuring the quality consistency of each batch of products.

[0028] In summary, the all-in-one machine of the present invention is a pasta processing equipment that integrates refrigeration, proofing and heating functions, which can make the raw pasta proof at the terminal, and realize the sequential operation of refrigeration, proofing and heating of the raw pasta in the processing chamber 102, avoiding environmental exposure caused by manual transfer, and converting the raw pasta from a low-temperature dormant state to a hot food product in a short time when sold. Compared with the traditional process of reheating frozen cooked food, it not only retains the mellow wheat aroma and ester flavor substances produced by natural fermentation of the raw dough, but also avoids the problems of dry and hard skin and hard core layer of the reheated product caused by the breakage of starch chains. This production mode of immediate proofing and steaming ensures that consumers can obtain the unique fermentation aroma of pasta products within the best tasting period in a timely manner.
