AI Technical Summary
The mixing racks of existing electric ice cream machines use steel scrapers, which cause noise, wear, and uneven mixing due to the gap between the mixing drum wall and the scraper. In addition, the mixture tends to stick to the drum wall, affecting mixing efficiency and causing the machine to jam.
The food-grade engineering plastic scraper, made of nylon PA6, combined with an L-shaped mixing rack and spring structure, ensures that the scraper adheres closely to the barrel wall, thereby thoroughly scraping away the mixture, preventing jamming, and improving mixing uniformity and efficiency.
It achieves thorough and uniform mixing, reduces mixing time, improves work efficiency, avoids equipment jamming, and has a simple structure that is easy to install.

Abstract
Description
Technical Field
[0001] This utility model relates to a mixing rack, and more particularly to a mixing rack for an electric ice cream machine. Background Technology
[0002] The process of making ice cream using an electric ice cream machine is as follows: First, mix milk, eggs, sugar, and other seasonings and pour the mixture into the mixing bowl of the ice cream machine. Turn on the power, and the mixing rack inside the mixing bowl begins to rotate and mix. At the same time, the cooling device surrounding the mixing bowl also begins to cool. Mix for about 30 minutes to an hour, then remove and freeze in a refrigerator until set. My utility model patent (patent number 202320633315.4, a machine for making ice cream and shaved ice) is similar to existing electric ice cream machines in that the scraper of the mixing rack is made of steel. However, using a steel scraper requires a 1-2 mm gap between the mixing bowl wall and the steel scraper. If no gap is left, the steel scraper will be tightly pressed against the steel mixing bowl wall without any gap. Therefore, when the mixing rack rotates, the steel plate will rub against the steel bowl, producing not only a harsh noise but also damaging the mixing bowl wall. Furthermore, and more seriously, because there is a 1-2 mm gap between the mixing drum wall and the steel scraper, the ice cream mixture gradually sticks to and freezes on the mixing drum wall, making it difficult to scrape clean. As the mixing and cooling time increases, the mixture accumulates thicker and thicker, making it impossible to achieve thorough and uniform mixing of all the ice cream mixture. When the thickness exceeds the gap and freezes hard, it can also cause the mixing rack to become stuck and jam, affecting the operation. Summary of the Invention
[0003] The purpose of this invention is to provide a mixing rack for an electric ice cream machine that is made of engineering plastic, has good toughness, can thoroughly scrape clean, and does not jam.
[0004] The technical solution adopted by this utility model is that the mixing rack of this electric ice cream machine has an L-shaped mixing rack 1 connected and fixed on the left side by a bushing with through holes in the upper and lower parts, and an L-shaped mixing rack 2 connected and fixed on the right side. The L-shaped mixing rack 1 and L-shaped mixing rack 2 are not on the same plane, and there is a plane angle greater than zero degrees between them. The bottom ends of the two are one in front and one in back. Each of the uprights of the L-shaped mixing rack 1 and L-shaped mixing rack 2 is provided with a slot on the outside. Each slot is fitted with a scraper with springs on both ends of the inner side. The scraper is a food-grade engineering plastic plate made of nylon PA6.
[0005] Due to the adoption of the above technical solution, this utility model has the following beneficial effects: First, the scraper is a food-grade engineering plastic sheet made of nylon PA6. Nylon PA6, also known as polyamide 6, is a common synthetic fiber and engineering plastic. Its performance characteristics include high strength, toughness, and wear resistance, enabling it to withstand significant external forces and impacts. It can be used at higher temperatures, with a heat distortion temperature of 150℃. It exhibits good resistance to many chemicals, such as oils and solvents. Nylon PA6 has a certain degree of hygroscopicity, which increases the material's toughness after absorbing moisture. Therefore, a food-grade engineering plastic sheet made of nylon PA6, used as a scraper, offers high strength, good toughness, and wear resistance. Secondly, each of the L-shaped mixing racks (first and second) has a slot on the outer side of its uprights. Each slot houses a scraper with springs on both inner ends. Under the spring force, the scraper remains firmly against the bucket wall, scraping away the ice cream mixture and preventing it from sticking or freezing to the mixing bucket wall. This thorough scraping ensures complete and even mixing of the ice cream mixture without jamming. Thirdly, it boasts high efficiency, reducing mixing and cooling time from over 30 minutes to less than 25 minutes. Fourthly, it has a simple structure, is easy to manufacture, install, and disassemble. Attached Figure Description

[0011] Example 1, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the mixing rack of this electric ice cream machine has a bushing 2 with through-holes 1. An L-shaped mixing rack 3 is fixed to the left side, and an L-shaped mixing rack 4 is fixed to the right side. The L-shaped mixing racks 3 and 4 are not on the same plane; they have a plane angle greater than zero degrees. This means that the uprights of both L-shaped mixing racks 3 and 4 are not perpendicular to the bottom of the mixing tank, and their bottom ends are positioned at opposite ends, creating an inclined configuration. This design allows for a larger mixing space, enabling the ice cream mixture in the middle and bottom of the mixing tank to rise and achieve thorough mixing. Each upright of the L-shaped mixing racks 3 and 4 has a slot 5 on its outer side. Each slot 5 holds a scraper 7 with springs 6 on both inner ends. The scraper 7 is made of food-grade engineering plastic, nylon PA6. It is particularly important to note that... Figure 4 This is a top-view perspective view of the old-fashioned steel scraper mixing rack installed inside the mixing tank, rather than a top-view perspective view of the mixing rack installed inside the mixing tank of this utility model. The purpose of providing this view is to facilitate understanding of the technical solution of this utility model.
[0012] Example 2: As described in Example 1, the mixing rack of an electric ice cream machine has a curved steel strip 8 fixedly connected between the two bottom ends of an L-shaped mixing rack 3 and an L-shaped mixing rack 4. Its function is to stir the ice cream mixture at the bottom of the mixing tank.
[0013] Example 3: As described in Example 1 or 2, the stirring rack of an electric ice cream machine has a sleeve hole 9 at each end of the inner side of the scraper 7, and a spring 6 is inserted into the sleeve hole 9. There are several methods to install the spring 6 on the scraper 7. One method is to first drill two non-through sleeve holes at both ends of the scraper 7, and then insert the spring. Alternatively, an adhesive method can be used.
