Description

Technical Field

[0001] The utility model belongs to the field of food detection equipment, in particular to a device for detecting the water content of milk powder. Background Art

[0002] Milk powder is a kind of instant food with rich nutrition. After the production and processing of milk powder is completed, the staff needs to sample and test the finished milk powder to ensure that the various parameters of the milk powder meet the factory requirements.

[0003] When testing milk powder, water content testing is an essential step. Usually, the staff needs to put the milk powder sample into the testing device first, and then weigh the milk powder sample through the testing device to determine the initial weight of the milk powder sample. Next, the milk powder sample is heated to 105°C through the testing device to evaporate the water in the sample, and the weight of the sample after the water evaporates is recorded. At this point, the staff can calculate the water content of the milk powder based on the weight of the sample after the water evaporates and the initial weight.

[0004] However, the sample heating efficiency of the existing detection device is low, and the heat generated by the heat source inside the device cannot be concentrated and transferred to the sample, which will reduce the heating speed of the milk powder sample. In addition, when using the traditional detection device, the milk powder sample is prone to accumulation inside the device, which will reduce the speed of water evaporation, thereby further affecting the detection efficiency of the water content of the milk powder.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0032] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0033] A device for detecting water content in milk powder, the structure of which can be Figure 1-Figure 7 As shown in the figure, in this embodiment, the milk powder moisture content detection device includes: a base 1, a thermal conductive lining 4 and a material receiving seat 5, wherein the base 1 is used to provide a mounting base for other components in the device, the material receiving seat 5 is used to carry the milk powder sample to be detected, and the thermal conductive lining 4 is used to improve the thermal utilization rate of the device.

[0034] In order to conveniently accommodate the thermal conductive lining 4 and the material receiving seat 5, a receiving groove 11 is provided on the top surface of the base 1, and a flip-open top cover 3 is provided on the top of the receiving groove 11. When assembling the device, the thermal conductive lining 4 should be arranged inside the receiving groove 11, and the material receiving seat 5 is detachably arranged in the thermal conductive lining 4. When in use, the staff can control the opening and closing of the receiving groove 11 by flipping the top cover 3, so as to facilitate the loading or unloading of the material receiving seat 5 into or out of the device.

[0035] Optionally, in order to realize the connection between the top cover 3 and the base 1, a connection seat 12 may be provided on the top surface of the base 1 in this embodiment. During assembly, one end of the top cover 3 should be hinged to the connection seat 12, so that the top cover 3 can be flipped around the hinge point. Accordingly, a buckle groove 33 may be provided on the side wall of the top cover 3 away from the connection seat 12, so that the staff can apply a rotational torque to the top cover 3 through the buckle groove 33, thereby driving the top cover 3 to flip.

[0036] In order to facilitate the staff to judge the weight change of the milk powder sample during use, the base 1 should also be provided with an equipment cavity, and a weighing assembly 2 should be provided in the equipment cavity. Accordingly, a first connecting hole connected to the equipment cavity should be provided on the bottom surface of the receiving groove 11, a second connecting hole 41 opposite to the first connecting hole should be provided on the bottom surface of the thermal lining 4, and a connecting column 52 should be provided on the bottom surface of the material receiving seat 5. When the material receiving seat 5 is installed in the thermal lining 4, the connecting column 41 will be inserted into the equipment cavity along the first connecting hole and the second connecting hole 41, so that the bottom end of the connecting column 52 abuts against the weighing assembly 2, thereby facilitating the weighing assembly 2 to weigh the weight of the milk powder sample.

[0037] It should be noted that the weighing assembly 2 described in this embodiment can be a common weighing device in the prior art (such as an electronic balance or a weighing sensor, etc.). When the material receiving seat 5 is installed in the heat conductive lining 4, the bottom end of the connecting column 52 will be against the detection end of the weighing assembly 2, so that the weighing assembly 2 can weigh the weight of the material receiving seat 5 and the milk powder sample to be tested. Accordingly, when using it, the staff should also peel the weighing assembly 2 according to the weight of the material receiving seat 5, so that the weight displayed by the weighing assembly 2 is the real-time weight of the milk powder sample.

[0038] Optionally, in order to prevent the heat inside the receiving tank 11 from affecting the service life of the weighing assembly 2, this embodiment further provides a heat insulation pad 7 inside the receiving tank 11. Figure 4 As shown, the thermal insulation pad 7 should be located between the bottom surface of the accommodating groove 11 and the bottom surface of the thermal conductive lining 4, and an avoidance hole 71 corresponding to the first connecting hole is provided on the thermal insulation pad 7 to facilitate the connecting column 52 to smoothly enter the interior of the equipment cavity.

[0039] Figure 2This is a schematic diagram of the structure of the top cover 3 of the device in an open state. Figure 3 The exploded diagram of the device is shown in the figure. As shown in the figure, a receiving groove 51 for accommodating milk powder samples is provided on the top surface of the receiving seat 5, and a halogen heating lamp 31 is provided on the bottom surface of the top cover 3. When in use, the staff can put the milk powder sample to be tested into the receiving groove 51, and turn on the halogen heating lamp 31 after the top cover 3 is closed, so as to heat the inside of the receiving groove 11 with the help of the halogen heating lamp 31, so that the water in the milk powder sample to be tested can be evaporated quickly. Subsequently, the staff can calculate the water content in the milk powder sample to be tested by the change in the reading before and after the weighing component 2 is heated, so as to determine whether the milk powder sample to be tested meets the factory requirements.

[0040] Optionally, since the heat source in the device (i.e., the halogen heating lamp 31) is located above the material receiving trough 51, the material receiving trough 51 can be configured as a truncated cone-shaped groove with the large end facing upward, thereby increasing the heating area of ​​the milk powder sample inside the material receiving trough 51.

[0041] Since the device is provided with a heat-conducting lining 4 inside the receiving tank 11, when the halogen heating lamp 31 is turned on, the heat-conducting lining 4 can absorb the heat inside the receiving tank 11 and transfer the heat to the inside of the material receiving seat 5. Compared with the traditional radiation heat transfer method, the presence of the heat-conducting lining 4 can improve the heat conduction efficiency inside the device, so that the milk powder sample inside the material receiving tank 51 can reach the water evaporation temperature faster, thereby speeding up the detection of the water content of the milk powder.

[0042] In addition, in order to improve the heat conduction effect between the heat conductive lining 4 and the material receiving seat 5, as Figure 5 and Figure 6 As shown, a plurality of heat-conducting fins 42 may be provided on the inner side wall of the heat-conducting lining 4, and a plurality of heat-conducting grooves 53 may be provided on the outer side wall of the material receiving seat 5. When the material receiving seat 5 is installed into the heat-conducting lining 4, the heat-conducting fins 42 will be inserted into the heat-conducting grooves 53. The cooperation of the heat-conducting fins 42 and the heat-conducting grooves 53 can increase the contact area between the heat-conducting lining 4 and the material receiving seat 5, so that the heat can be transferred to the material receiving seat 5 faster.

[0043] Optionally, in order to further improve the heat utilization rate of the device, a heat insulating ring 34 may be provided on the bottom surface of the top cover 3, and the outer diameter of the heat insulating ring 34 should be equal to the inner diameter of the receiving groove 11. Figure 1 In the closed state shown, the heat insulating ring 34 will block the joint gap between the top cover 3 and the base 1, thereby preventing heat loss from the receiving groove 11.

[0044] In actual operation, since the particle size of milk powder is small, milk powder samples are easily accumulated inside the detection device when the water content is detected. When the milk powder samples accumulate, the evaporation rate of water will be affected, which will reduce the efficiency of milk powder water content detection. To solve this problem, this embodiment further provides a rotatable powder distribution member on the top cover 3, such as Figure 3 and Figure 7 As shown, the powder distributing member is provided with a plurality of air holes 63, and the bottom surface of the powder distributing member is provided with a plurality of powder distributing needles 64. When in use, the air holes 63 on the powder distributing member can facilitate the evaporated water to leave the device, and the staff can also drive the powder distributing member to rotate, so as to use the powder distributing needles 64 to spread the milk powder sample inside the receiving tank 51, thereby reducing the difficulty of water evaporation.

[0045] Specifically, the powder distributing member may include a connecting section 61 and an operating section 62, wherein the operating section 62 is arranged above the connecting section 61, and a mounting hole 32 for accommodating the connecting section 61 is provided on the top cover 3, the outer diameter of the connecting section 61 is equal to the inner diameter of the mounting hole 32, and the outer diameter of the operating section 62 is larger than the outer diameter of the connecting section 61. During assembly, the connecting section 61 can be rotatably inserted into the mounting hole 32. When the top cover 3 is in a closed state, the powder distributing needle 64 at the bottom of the connecting section 61 will be inserted into the material receiving groove 51. At this time, the staff can drive the powder distributing member to rotate through the operating section 62, so that the powder distributing needle 64 moves inside the material receiving groove 51, thereby spreading the milk powder sample.

[0046] Optionally, in order to improve the powder dispersing effect of the powder distributing needle 64, the distances between any two powder distributing needles 64 and the rotation center of the powder distributing member in this embodiment are different. Figure 7 As shown, when four powder distribution needles 64 are provided on the powder distribution member, since the distances between any two powder distribution needles 64 and the rotation center of the powder distribution member are different, when the powder distribution member rotates 360°, four circular grooves with different diameters will be formed on the milk powder sample inside the receiving trough 51. When the milk powder sample is heated by the halogen heating lamp 31, the presence of the circular grooves can not only increase the surface area of ​​the milk powder sample, accelerate the milk powder sample to reach the temperature of water evaporation, but also facilitate the separation of water from the milk powder sample, thereby increasing the speed of milk powder water content detection.

[0047] As an optional implementation of this embodiment, in order to improve the operational convenience of the device, a display screen and a plurality of control buttons may also be provided on the base 1. During assembly, the plurality of control buttons should be electrically connected to the weighing component 2 and the halogen heating lamp 31, respectively, so that the staff can control the switch of the weighing component 2 and the halogen heating lamp 31 through the control buttons. Correspondingly, the display screen should be electrically connected to the weighing component 2, so that the weight indication of the milk powder sample can be displayed with the help of the display screen. In addition, a battery may also be provided inside the base 1, and the battery should be electrically connected to other electrical components inside the device, so as to provide energy supply for the electrical components.

[0048] The effects of the above scheme are described below:

[0049] This embodiment provides a milk powder water content detection device, which can absorb the heat inside the receiving tank through the heat-conducting lining and transfer the heat to the inside of the bearing seat, thereby improving the heat conduction efficiency of the device. At the same time, the device can also use the powder distribution needle to spread the milk powder sample accumulated inside the receiving tank, so that a groove that is easy for water to evaporate is formed on the milk powder sample, thereby increasing the evaporation rate of water, and thus being able to complete the milk powder water content detection work more efficiently.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
