Overview of Purple Sweet Potato Powder

Purple sweet potato powder is made from fresh, high-quality purple sweet potatoes through processes such as peeling and drying. It retains all the dry matter of purple sweet potatoes except for the skin, including protein, fat, carbohydrates, vitamins, minerals, and dietary fiber. After rehydration, the color, aroma, taste, and texture of the purple sweet potato powder are identical to those of freshly steamed and mashed purple sweet potatoes. The nutritional content of purple sweet potatoes is significantly higher than that of ordinary sweet potatoes. Long-term consumption has benefits such as lowering blood pressure, enriching the blood, replenishing energy, moistening the lungs, and nourishing the skin. Additionally, it is a weight-loss food that can effectively prevent arteriosclerosis, enhance immune function, eliminate free radicals in the body, inhibit DNA synthesis in cancer cells and their division and growth, and prevent the occurrence of cancers such as gastric cancer and liver cancer.

Overview of Purple Sweet Potato Powder Dryer:
Roller Scraper DryerIt is a continuous drying equipment of the internal heating conduction type. The rotating drum picks up a film of material of a certain thickness from the material trough below. Heat is delivered through pipes to the inner wall of the drum, conducted to the outer wall, and then transferred to the material film, causing the moisture in the film to evaporate and be removed, thereby drying the wet material. The dried material is scraped off the drum surface by a scraper installed on the drum, then falls onto a screw conveyor placed below the scraper, which collects and packages the dry material.

Dried Purple Sweet Potato Powder DryerScope of Application:
Yeast, baby food, rice paste, food additives for special processes, animal and plant feed, milk powder for chocolate making, starch modification production processes, potato flour, chemical dyes, pharmaceuticals, yeast series, etc.

Process characteristics of purple sweet potato powder dryer:
1. The body of the Haomai new-type double-drum scraper dryer breaks away from traditional designs. This structure and material are extremely robust and exceptionally stable, with a nearly ** weight distribution.
2. The advanced safety system helps provide active protection for the cylinder body.
3. Mature shock absorption and avoidance technology can provide more complete and precise protection.
4. The precision of the cylinder and the machine body has reached 1/15th of the thickness of a human hair, ensuring operational stability superior to that of similar American products.

Advantages of Purple Sweet Potato Powder Dryer:
1. High drying rate: Due to the thin material film and the consistent direction of heat and mass transfer, the surface of the material film can maintain an evaporation intensity of 70-160 kg H₂O/(m²·h), which is more than 50% higher than that of conventional domestic scraper dryers.
2. High operational flexibility and wide applicability. Many drying factors of the drum dryer can be adjusted, such as the concentration of the feed, the concentration of the coating, the thickness of the coating film, the temperature of the heating medium, and the rotational speed of the drum. These factors can all alter the drying efficiency of the drum dryer without interfering with one another. This brings great convenience to drum drying operations, enabling it to adapt to the drying of various materials and meet different production capacity requirements.
3. High Thermal Efficiency: It is the first double-drum scraper dryer in China with a thermal efficiency exceeding 90%.
4. Short drying time: The drying cycle for materials is generally only 10-300 seconds, making it suitable for heat-sensitive materials. If the drum dryer is placed in a vacuum chamber, it can operate under reduced pressure conditions.

5. Small footprint: The equipment occupies only one-third of the area of a drying tower, reducing the factory investment cost for manufacturers.

6. Low energy consumption: Compared to spray dryers, it saves 80% in energy consumption, while its output is three times higher.
