A new type of respiratory-type veneer press drying process - details see: https://www.machineto.com/dry-hot-press-10345931

Local companies are my many years of development and production experience, from the technical department the unique design of the new veneer dry pressing machine, with more than plywood manufacturer in practice proved to be an efficient, new generation of energy-saving drying equipment. It is suitable for peeling of desiccant drying, the whole flat. Dried veneer roughness, and full contraction. At hot-pressing machine installed on symmetric synchronous closing spring lever body so that all floors of the press in hot plate and can be contacted simultaneously or released; hot plate by the specialized post-production, with Express, exhaust steam function; rack using the framework of institutions, progress oil mouth-style fuel tanks, installation convenience, low investment foundation. Using saturated steam or heat conducting oil as a set of heating hot plate, producing high efficiency, low consumption, the entire board process scheduled by the electrical automation and control technology, operation, easy process.

A new type of respiratory-type veneer press drying process
Wood drying wood production and processing are important in one important aspect, and at the dry veneer plywood, parquet substrate, container flooring, artificial wood (also known as Wood Technology), etc. in the same production process is a crucial process . At present most of the enterprises with the use of Net dryer, roller dryer or artificial methods of drying veneer drying, drying the first two costs are high, electricity costs, energy costs, SBC easy cracking, breakage and potential hazards; which required many venues and staff, but also for drying
After the veneer moisture content can not be controlled and protected.
Wood drying wood is to exclude water. Under normal circumstances, the wood moisture content is higher than the internal and external moisture content, wood heating, timber outside temperature is higher than the internal temperature, moisture gradient force the water from the internal to external mobile, while the temperature gradient force the water from external to internal Mobile, these two opposite direction of water moving against each other, with the result that timber from the place near the surface showed a slow-moving water, thus the resistance of the drying process. In ensuring the quality of drying under the premise improve drying rate are the basic principles of drying, the traditional drying methods improve only by the drying temperature to solve the drying rate, and now a new type of press drying process to solve the problem.
We use specially processed hot plate, a way to contact conduction, direct heating of wood veneer. Because of heating plate heating temperatures are high, with close contacts do timber, heat transfer, and slow-moving timber internal moisture quickly be broken, the temperature quickly reach high temperatures, steam pressure transient improve and promote the internal water timber to the outside of the mobile . In order to make large amounts of water in a large area of the cubicle emitted a timely manner, the hot press drying veneer board specifically set up a large density of vapor permeability trough, so that a large number of steam from the rapid adoption of a trench to reach the purpose of fast-drying, this technology is not easy for some dry hard species are particularly effective.
Because of the role of stress, the shrinkage of wood will do greater than normal shrinking do to increase density, dimensional stability is improved, has played the role of leveling veneer. However, excessive stress, not only will bring a greater volume loss, and will produce surface hardening and cracking. To this end veneer dryer hot hot in the entire multi-layer boards closed institutions, the design of synchronous closed system so that each floor plate of the closed interval between the same, up and down each cubicle pressure on the veneer of the same force and through the hydraulic control system of random adjustment stress.
Timber drying, the moisture content decreased at the course will have a certain amount of contraction, and because of the different species, the volume contraction also not the same. Press drying process, the hot plate and by drying veneer Lamination contacts are, if not promptly torn off and will have a single crack situation. The use of synchronous closed system solves this problem. Press drying machine with PLC system settings of the veneer drying process breathing procedures, when used under different circumstances to determine the respiratory rate and breathing time, to allow full contraction of veneer and distributed water.
Veneer press drying machine with the traditional mesh belt, roller dryer, compared with power (power is only 11KW), Province of heat (thermal energy consumption of only 30 ~ 400,000 kcal), the workshop covers an area of less (only 10 square meters), the production of high efficiency (can be dry every day around 20m3) Operation and Maintenance is simple, and low day-to-day wear and tear, it will give SBC the popularity of drying technology bring new progress.
