Description

Technical Field

[0001] The utility model relates to the field of food baking release oil, in particular to a mold volume testing device used for testing the release effect of baking release oil. Background Art

[0002] Baked goods are quick and convenient to consume, and have become the breakfast of choice for many young consumers. Some consumers are also gradually developing the habit of eating desserts or afternoon tea after meals. As the consumption of baked goods shifts from festive occasions to daily life, the frequency of consumption is expected to increase further. Therefore, with the rapid development of the national economy, the baked goods industry has a huge market potential. The production and operation scale of the baking industry has also grown from small bakeries to today's large-scale corporate production. Traditional baking release fat substitutes are difficult to spray and have poor demolding effects, making them inadequate for industrial production. Therefore, the promotion and application of easy-to-spray, excellent demolding properties for baking food release oils is of great significance. Currently, domestic baking fat companies have achieved considerable development and scale, becoming the main source of supply for domestic baking fat demand.

[0003] The main function of food baking release oil is to prevent adhesion between the cake and the mold during the baking process, allowing the cake to be easily and completely released from the baking mold after baking. Considering the release properties alone, an excellent release agent should have the following characteristics: ① It can form a uniform film with good demoulding properties and no residue on the mold surface; ② It is easy to apply or spray; ③ It has good chemical stability and is resistant to high temperatures; ④ It does not corrode the mold or contaminate the finished product, and has low odor and toxicity. ⑤ It is environmentally friendly and has good biodegradability. Among them, the demoulding effect is a key indicator that needs to be evaluated for food baking release oil products. Currently, according to relevant literature reports and actual applications, the rapeseed replacement method is often used to evaluate the adhesion rate after baking demoulding.

[0004] The rapeseed displacement method is a working principle of a special measuring instrument used to measure the volume of bread, steamed buns, pastries and various irregular solid foods. This method uses rapeseed as a displacement medium to measure the volume of food. During the specific operation, first put an equal volume of rapeseed into a container, and then put the food to be measured into another sample chamber connected to the container. In this way, the food will occupy the volume originally used to displace the rapeseed, and the volume of the food can be obtained by measuring the change in the rapeseed volume. This method is suitable for volumes less than 1000cm 3To determine the volume value of food, rapeseed with a particle size of 1 to 2 mm is used as the internal filling. In order to reduce the error, rapeseed with small particles should be selected because the volume error is smaller. The operation process of using this method to test the demoulding effect is relatively cumbersome. No matter how small the rapeseed is, there will still be gaps between the large number of rapeseeds. Relying on the naked eye to read the volume of rapeseed will also lead to errors in volume measurement, and the tiny rapeseed is easy to stick to the baking residue on the mold and is difficult to clean. In addition, this method is inefficient in evaluating the demoulding effect of multiple batches of demoulding oil, and is time-consuming and labor-intensive. Therefore, it is necessary to design a mold volume testing device for testing the demoulding effect of baking demoulding oil to solve the above-mentioned problems. Utility Model Content

[0042] like Figure 1 and 2 The utility model is a specific example of a mold volume testing device for testing the demoulding effect of baking demoulding oil. In this embodiment, the mold adopts a baking tray 15, and the power supply of the annular electromagnet 7 adopts an external power supply, including a round rod 1, a driving mechanism, a non-slip handle 4, a filling column 5, and a filling liquid 6.

[0044] The driving mechanism includes: a driving mechanism body 9, a driving mechanism switch 10, a driving mechanism battery box 11, a transmission motor 3, and a driving mechanism display screen 2;

[0045] The driving mechanism body 9 is the main body for controlling the device and is a hollowed-out cylindrical body. The driving mechanism display screen 2 is located on the driving mechanism body 9. The driving mechanism switch 10 is located on the driving mechanism body 9 and can turn the driving mechanism display screen 2 on and off. The driving mechanism battery box 10 is located on the driving mechanism body 9 and provides power to the driving mechanism.

[0046] The round rod 1 has a rack on one side, and the lower end of the round rod 1 is connected to the piston 12; the round rod 1 passes through the driving mechanism body 9, and the piston 12 is tightly fitted with the filling column body 5;

[0047] The transmission motor 3 is equipped with an electromagnetic circuit breaker. The transmission motor 3 is installed in the driving mechanism body 9 and has its own switch. A gear is provided at the transmission end and connected with the side of the round rod 1 having a rack, so that the round rod 1 is controlled by the transmission motor 3 and performs piston movement up and down during operation.

[0048] The filling column body 5 is made of a transparent special plastic material, and two anti-slip handles 4 are provided on both sides of the upper end to facilitate the operator to control the device during the test and prevent it from slipping or loosening.

[0049] The filling column 5 is filled with an appropriate amount of filling liquid 6, which is water with dye added, so as to facilitate observation of the filling situation when the filling bag 14 is filled into the groove to be tested on the baking tray 15.

[0050] The lower end of the filling column 5 is connected to the circular mold pressing plate 13, and the filling bag 14 is installed in the center of the mold pressing plate 13. The filling bag 14 is made of transparent latex material, has good filling effect, and is easy to replace.

[0051] The mold pressing plate 13 is made of a transparent special plastic material and can be replaced with different models according to the different sizes of the grooves to be tested in the baking tray 15. A circle of annular electromagnets 7 is provided at its edge, which is controlled by an annular electromagnet switch 8.

[0052] The driving mechanism body 9 is provided with a snap-fit structure, which can be snap-fitted and fixed with the anti-slip handle 4 of the filling column 5 below it.

[0053] Working principle:

[0054] 1) Before baking, secure the drive mechanism body 9 to the filling column 5 with a snap fastener, or secure the drive mechanism body 9 to the filling column 5 with a bracket. Place a clean baking tray 15 on the countertop. The non-slip handle 4 on the filling column 5 prevents slipping and secures the drive mechanism body 9 during use. Select a mold platen 13 suitable for the baking tray 15. Place the mold platen 13 at the lower end of the device in the center of the test groove of the baking tray 15, and ensure that the filling bag 14 falls completely into the test groove of the baking tray 15. Turn on the annular electromagnet switch 8, so that the annular electromagnet 7 located on the mold platen 13 has a strong magnetic force, firmly adsorbing and fixing the device to the baking tray 15.

[0055] 2) After the device is fixed, turn on the drive mechanism switch 10 located on the drive mechanism body 9, the drive mechanism display screen 12 lights up, and the display reading is 0mL. Then turn on the switch of the transmission motor 3, the transmission motor 3 starts to operate, driving the round rod 1 with a rack on one side to start operating downward. The round rod 1 squeezes the filling liquid 6 into the filling bag 14 at a constant speed through the piston 12. During this filling process, the reading of the drive mechanism display screen 12 continues to increase. The approximate filling situation in the test groove of the baking tray 15 can be observed through the mold pressing plate 13 made of transparent special plastic material. When the filling liquid 6 is completely filled, the round rod 1 can no longer continue to advance due to reaching the set power threshold. The reading of the drive mechanism display screen 12 is stable and maintained for 3s. The electromagnetic circuit breaker of the transmission motor 3 is activated, causing the transmission motor 3 to stop running. The volume reading displayed on the drive mechanism display screen 12 at this time is recorded as V1.

[0056] 3) After the filling volume test is complete, the switch on the transmission motor 3 is turned on again. The transmission motor 3 begins to reverse, driving the round rod 1 upward. The filling liquid 6 is uniformly withdrawn from the filling bag 14 into the filling column 5 until the reading on the drive mechanism display 12 reaches 0 mL. The transmission motor 3 stops operating. The ring electromagnet switch 8 is turned off. The ring electromagnet 7 loses its magnetism and becomes loose from the baking tray 15. The device is then removed from the baking tray 15 and prepared for the next test.

[0057] 4) After baking, remove the cake from the test groove on baking pan 15. After baking pan 15 has fully cooled to room temperature, repeat steps 2) and 3) above. The resulting volume reading is V2. The difference between V1 and V2 and their ratio can be used to calculate the sticking rate of the baking residue in the experimental group, which can be used to evaluate the release effect of different food release oils.
