Description

Technical fields:

[0001] This invention relates to a melt liquefaction technology. Background technology:

[0002] The melting of some solid materials, such as chocolate, is usually done by placing chocolate blocks into a heating pot. This melting method takes a long time due to the large size of the chocolate blocks, making it difficult to achieve continuous melting production. If the chocolate is first crushed and then put into the heating pot for melting, the crushed chocolate is prone to sticking to the crushing equipment due to the nature of chocolate. This not only affects the continuous crushing process, but also causes the chocolate to deteriorate and result in losses if it sticks to the crushing equipment for a long time. Summary of the Invention:

[0003] The purpose of this invention is to provide a liquefier that has a short melting time and is suitable for continuous melting production.

[0004] The present invention is implemented as follows: it includes a frame, a melting pot mounted on the frame, and a crushing mechanism mounted above the melting pot. The crushing mechanism includes a feeding section and a crushing and melting section. The crushing and melting section includes a channel with its upper end connected to the feeding section and its lower end guiding to the melting pot, and two or more rolling rollers mounted in the channel and driven to rotate by a power source. The outer surface of the rolling rollers is provided with several teeth, and a medium interlayer is provided inside the rolling rollers. The interlayer is connected to a medium source that controls the temperature of the rolling rollers.

[0005] During operation, large pieces of material to be melted (such as chocolate) are fed into the feeding section of the crushing mechanism. Under their own gravity, the large pieces enter the working range of the rollers. A medium is introduced into the interlayer of the rollers, raising their temperature to the temperature of the molten material. Power drives the rollers to rotate relative to each other, and the large pieces fall between two adjacent rollers, where they are crushed and squeezed by the teeth on the rollers. The crushed smaller pieces fall into the melting pot and are heated and melted, while the material adhering to the rollers melts and drips into the melting pot. Because the rollers have both crushing and melting capabilities, they prevent material from adhering to them, improve crushing efficiency, and prevent adhering material from affecting the subsequent crushing of large pieces. Melting only occurs after material has been crushed, and heating occurs during the crushing process, resulting in short melting time and high efficiency. The molten liquid material is then transported away through a power transmission system at the bottom, thus achieving continuous melting and continuous production.

[0006] Compared with existing technologies, this invention has the advantages of short melting time and suitability for continuous melting production. Attached image description:

[0011] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0012] Example 1: As Figure 1 , 2 As shown, the present invention includes a frame 1, a melting pot 2 mounted on the frame 1, and a crushing mechanism a mounted above the melting pot 2. The crushing mechanism a includes a feeding section 3 and a crushing and melting section 4. The feeding section 3 is a funnel-shaped channel. The crushing and melting section 4 includes a channel 4a with its upper end connected to the funnel-shaped channel 3 and its lower end guiding the melting pot 2. Two rolling rollers 4c, driven to rotate by a power source 4b (including a motor and a speed-changing mechanism), are mounted inside the channel 4a. The outer surface of the rolling rollers 4c is provided with several teeth 4d. A medium interlayer 4e is provided inside the rolling rollers 4c. The medium interlayer 4e is connected to a medium source b that controls the temperature of the rolling rollers 4c. The first rolling roller 4c is located at the upper left, and the second rolling roller 4c is located at the lower right. When the teeth 4d on the two relatively rotating rolling rollers 4c meet, the teeth 4d on the first rolling roller 4c are located between the two teeth 4d on the second rolling roller 4c.

[0013] like Figure 2 As shown, the output end 5a and return end 5b of the medium source 5 (such as heated water) are respectively connected to the medium inlet and medium outlet of the medium interlayer 4e set in the roller 4c. Constant temperature water is continuously introduced into the medium interlayer 4e set in the roller 4c and then flows back to the medium source 5, so that the temperature of the roller is kept constant at the process temperature, so as to efficiently crush large pieces of material.

[0014] Example 2: As Figure 2 As shown, this embodiment is based on embodiment 1, with three rolling rollers 4c. The third rolling roller 4c is located to the lower left of the second rolling roller 4c. When the teeth 4d on the relatively rotating second rolling roller 4c and the third rolling roller 4c meet, the teeth 4d on the second rolling roller 4c are located between the two teeth 4d of the third rolling roller 4c.

[0015] Example 3: As Figure 3As shown, this embodiment is based on embodiment 1. The feeding section 3 is a transverse box-type chute. The inlet of the transverse box-type chute 3 is equipped with a movable cover 6. The outlet of the transverse box-type chute 3 is connected to the channel 4a of the crushing and melting section 4. There are four rollers 4c in the channel 4a. The four rollers 4c are arranged in a stepped manner from the material inlet on the side of the channel 4a. A baffle 7 is provided above the bottom roller 4c. When the teeth 4d on the two bottom rollers 4c that are rotating in opposite directions meet, the teeth 4d on one roller 4c are located between the two teeth 4d of the other roller 4c. The transverse box-type chute 3 makes it convenient for the operator to feed materials. At the same time, the cover 6 prevents heat loss and avoids the entry of external contaminants.

[0016] During operation, large pieces of material (such as chocolate) A to be melted are fed into the feeding section 3 of the crushing mechanism a. Under its own gravity, the large pieces of material A enter the working range of the roller 4c. A medium is introduced into the interlayer 4e of the roller 4c, raising the temperature of the roller 4c to the temperature of the molten material. The power source 4b drives the roller 4c to rotate relative to each other, and the large pieces of material fall between two adjacent rollers 4c, where they are crushed and squeezed by the teeth 4d on the roller 4c. The crushed small pieces of material fall into the melting pot 2 and are heated and melted, while the material adhering to the roller 4c is heated and melted, dripping into the melting pot 2. The molten material in the melting pot 2 can be circulated back into the melting pot 2 through the circulation loop of the power transmission system b to further accelerate the melting of the solid material in the melting pot. After the material in the melting pot 2 is fully melted, it is sent to the next process by the power transmission system b.

Claims

1. A liquefier, characterized in that, The device includes a frame, a melting pot mounted on the frame, and a crushing mechanism mounted above the melting pot. The crushing mechanism includes a feeding section and a crushing and melting section. The crushing and melting section includes a channel with its upper end connected to the feeding section and its lower end guiding the melting pot, and two or more rolling rollers driven to rotate within the channel. The outer surface of the rolling rollers is provided with several teeth, and a medium interlayer is provided inside the rolling rollers. The interlayer is connected to a medium source that controls the temperature of the rolling rollers. The molten material in the melting pot flows back into the melting pot through the circulation loop of the power transmission system. Large chunks of chocolate to be melted are fed into the feeding section of the crushing mechanism. Under their own gravity, the large chunks enter the working range of the rollers.
