Q: What are the core production directions of strawberry strip drying equipment in terms of process parameter settings?
Answer: Strawberries are heat sensitive materials with high moisture content, and the core direction of the process setting is "segmented temperature control and flow drying". Firstly, the equipment usually adopts a multi unit independent circulation design, and a gradient temperature (usually between 50 ℃ -150 ℃) needs to be set according to the drying characteristics of strawberries. In the early stage, higher temperature and faster speed can be used for rapid dehydration, and in the later stage, the temperature can be lowered and the residence time can be extended to prevent high temperature from damaging the color and nutrition of strawberries. Secondly, the hot air should flow up and down through a 12-60 mesh stainless steel mesh belt, using lateral unit circulation to increase the circulating air volume, making the hot air more penetrating, thereby shortening the distance of internal moisture evaporation and diffusion while ensuring that each strawberry is uniformly heated.
Q: What are the production operation directions of this equipment in terms of material loading and form protection?
Answer: The core of the operation direction lies in "evenly laying thin layers of material and preventing mechanical damage". In the feeding process, strawberry slices must be evenly and thinly distributed on the adjustable speed mesh belt through a dedicated fabric feeder. Stacking too thick is strictly prohibited to avoid increasing flow resistance and causing local incomplete drying. At the same time, the strawberry slices move slowly with the mesh belt in a stationary state inside the dryer. This continuous operation method avoids collisions and friction between materials, and does not cause mechanical damage to the shape of the materials, thus maximizing the preservation of the complete appearance and shape of the strawberry slices.
Q: What is the direction for adjusting and optimizing equipment based on the demand for finished product quality and production capacity?
Answer: The optimization direction mainly focuses on "flexible adjustment and multi machine series connection". On the one hand, users can freely adjust the operating speed of the mesh belt, the hot air circulation mode, and the temperature and air volume of each unit according to the moisture requirements of the final product, thereby accurately controlling the residence time and flow rate of materials in the machine; On the other hand, for large-scale production, multiple belt dryers are often used in series to form the initial drying section, intermediate section, and final drying section. This multi-stage combination method can not only better utilize equipment performance and make the drying process more uniform, but also cooperate with waste heat recovery systems to achieve efficient and energy-saving continuous industrial production.
