Overview

The dried fruit belt dryer is classified for drying sheet-like, strip-shaped, granular, and partially paste like materials with good breathability. Some materials can also be baked, burned, and matured.

Classification of dried fruit belt dryers

The structure is simple, easy to install, and can operate for a long time. In case of malfunction, it can also enter the box for maintenance, which is convenient for repair. The dried fruit belt dryer is composed of several unit sections. Each unit segment includes a circulating fan, heating device, separate or shared fresh air intake system, and exhaust system. The performance of the dried fruit belt dryer directly affects the quality and value of dried food.

Classification of dried fruit belt dryers

Here are several common types of belt dryers, including:

1. Multi stage belt dryer: Multi stage belt dryer is essentially composed of several single-stage belt dryers connected in series, and its operating principle is the same as that of single-stage belt dryers.

2. Impact belt dryer: The impact belt dryer is suitable for drying surface coatings of fabrics, tobacco leaves, substrates, and other thin sheet materials. The impact belt conveyor usually consists of two conveyor belts. The impact belt conveyor can be divided into unit segments for control. After the drying medium is humidified, some of it is discharged, while the other part is returned and mixed with fresh drying medium before circulating.

3. Single stage belt dryer: The dried material is evenly distributed onto the conveyor belt through the feeding device at the feeding end. Conveyor belts are usually made of perforated stainless steel sheets, driven by motors through gearboxes, and can be adjusted in speed. The interior of the drying machine is usually divided into several units to control operating parameters and optimize operations. There is an isolation section between the drying sections, where there is no circulation of drying medium.

4. Multi layer belt dryer: Multi layer belt dryer is commonly used in situations where the drying speed requirements are low, the drying time is long, and the process operating conditions can be maintained constant throughout the entire drying process. Set up partitions between layers to organize the directional flow of drying medium, ensuring uniform drying of materials. Multi layer belt dryer takes up less space, has a simple structure, and is widely used for drying grain materials. However, due to the need for multiple loading and unloading during operation, it is not suitable for dry and easily adhesive conveyor belts and materials that are not allowed to break.

The selection of a dried fruit belt dryer should consider multiple factors, including:

1. It is important to conduct small sample tests on dry materials. Therefore, for equipment suppliers, whether they have material testing equipment and experienced sample personnel is a direct way for customers to measure the manufacturer's true capabilities. Qualified belt dryer manufacturers are generally able to provide customers with a technical parameter report in a short period of time after material testing, including actual material evaporation, dynamic drying vacuum degree, distribution of drying temperature, feeding amount, actual drying time, actual product production capacity, unit energy consumption ratio, etc. This facilitates customers to choose equipment models and specifications that can meet production requirements.

2. Comprehensively assess the design level and manufacturing capability of the manufacturer. Manufacturers generally provide a preliminary technical design plan based on the material test report and the customer's production indicators and operating conditions, and provide a detailed explanation of the design reasons in the plan. The technical design scheme is an extremely important component in evaluating the manufacturing capability of manufacturers in vacuum belt dryers, especially the manufacturer's design description of key equipment technologies such as vacuum system design, heating system design, correction system design, cleaning system design, and feeding and discharging system design.
