At the equipment level, the heat loss of the microwave dryer is more serious, and there are still many shortcomings in the temperature detection. There are also some problems in the circuit control. Specifically, due to insufficient design, there is no adequate insulation and isolation between the various components of the equipment, and about 15% of the heat is absorbed by the outer metal material and then released into the operating space.
In addition, a portion of the heat is released to the job site, causing the temperature in the production environment to rise rapidly. Although the microwave dryer has invested a lot of power, the heat energy obtained is not ideal, and the energy waste is also serious.
In terms of temperature detection, some microwave dryers use the traditional temperature detection sensor, which makes the sensor sensitivity of the whole device low and the data conductivity is poor. Therefore, the limitations of these traditional components will make microwave dryers fail to meet the requirements of modern pharmaceutical processes.
When the microwave dryer has been working for a long time, the high-voltage diode in the circuit will also have a significantly lower high-pressure resistance. Due to the decrease in the high-pressure resistance, the high temperature will greatly increase the equipment failure rate, which seriously affects the product. The output of quality and qualified products will also significantly reduce production efficiency.
At the market level, experts said that the drying equipment currently used in the pharmaceutical industry is generally based on products with lower technical content, and there is still a certain gap compared with developed countries.
With China's emphasis on issues such as drug safety and environmental protection, pharmaceutical companies are more inclined to high-end, efficient equipment to ensure the competitiveness of enterprises. Therefore, in order to break through the pharmaceutical industry, the microwave dryer has to increase research and development efforts to gain the right to speak in the industry.
In addition, microwave dryers are widely used in the pharmaceutical industry because the equipment itself can be both dry and sterilized, so it is widely used in the pharmaceutical industry. However, in the pharmaceutical equipment, another major problem of microwave equipment in the pharmaceutical industry has arisen, lacking the authoritative voice from the industry.
Microwave dryers have to break through the bottleneck in order to gain more and greater opportunities in the market. For example, when microwave dryer companies have the productivity of high-quality products, they can use the Internet as a tool to promote branding, promote products, and enable customers to search for their products more quickly and conveniently on the Internet.
In addition, microwave dryer companies can also see the corporate brand in the professional industry media to improve the conversion rate of brand-oriented communication, which is also one of the necessary strategies. China Pharmaceutical Network is a portal for pharmaceutical machinery equipment industry. It can create a global network marketing service platform for professional users, and build a bridge of information interaction for domestic pharmaceutical machinery and related enterprises to realize business opportunities.
Of course, it is more fundamental that the microwave dryer enterprises should make technical improvements. For example, in terms of thermal energy loss, a layer of thermal insulation device can be installed between the magnetron and the thermal energy emitting head, and each magnetron and equipment gap are also filled with heat-insulating material to make each magnetic The heat generated by the control tube can be directly applied to the material and completely absorbed by the material on the conveyor belt.
When the heat energy has no space to be distributed, the loss is almost zero, the heat energy utilization rate is greatly increased, and the ambient temperature at the work site is also significantly reduced. Therefore, related companies need to improve the technology of microwave dryers to achieve more equipment possibilities, thus more in line with the requirements of modern pharmaceutical processes and GMP, and effectively improve the quality of pharmaceutical products.
A sleeping bag (sleeping bag) is a bag used for sleeping. The vast majority of sleeping bags on the market are labelled with a comfort temperature and an extreme temperature. The comfort temperature is the range of temperatures at which the user sleeps throughout the night, with a maximum and a minimum. The maximum comfort temperature is the kind of heat you feel in a sleeping bag but not when you are sweating profusely, and is generally defined as a sleeping bag with the zip open, arms outside and the head of the bag not tightened, etc.
Development history
Early humans were using animal fur to make warm clothing and sleeping mats, which are still used today, including by the Eskimos living near the Arctic. early 19th century explorers and mountaineers began to test different sleeping bag systems, early sleeping bags were filled with camel hair, which has excellent insulation properties, and then a hollow rubber air mattress was invented and used in the 18th century In 1861 Francis Fox Tuckett tested the first Alpine sleeping bag prototype, and in the mid-1860s the envelope sleeping blanket design began to be perfected, and near the ground are hollow rubber coating as a ground thermal insulation layer.
The role of the sleeping bag is simply to keep heat loss to a minimum, while the body inside the sleeping bag is constantly generating heat to keep warm, the amount of heat generated varies from individual to individual and from situation to situation, all sleeping bag temperature calibration systems are based on a standard human body, but such a standard human body basically does not exist. A sleeping body has approximately 75-100 watts of thermal power, which translates into approximately 47-55 watts per square metre based on the surface area of the body. The amount of energy produced by metabolism is very complex and relates to age, gender and even the amount of fat under the body, but by and large a fit young male always produces far more body heat than an older man or woman. The perception of cold is related to age and experience, with novices generally feeling colder than experienced climbers. People who work outdoors a lot feel warmer in cold conditions than those who work in an office a lot.
Use
Whether it is a down or synthetic cotton sleeping bag, try not to compress it up when it is not in use for a long period of time to keep it as fluffy as possible, and it is good to get a proper tan. The purpose of this is to maintain the nature of down and cotton and extend the life of the bag, especially for down sleeping bags, try to keep them in a special down sleeping bag storage bag (loose breathable cotton bag). As a personal hygiene product, try to avoid borrowing each other's sleeping bags.
When using a sleeping bag there are several ways to improve warmth.
Equip a good quality moisture-proof pad, which is very important, as anyone who camps a lot has experienced, if the cold air goes straight from the ground to the back, that kind of cold is unbearable; drink a hot drink before bed if possible, milk and fruit jelly are fine to warm up the body.
Eat a comfortable meal before bedtime, especially with carbohydrates (starches, sugars).
wearing a long set of thermal underwear and clean socks will be very effective.
wearing more clothes when the sleeping bag is not warm enough, or covering the sleeping bag with clothes and other items.
sharing a tent with a larger number of people.
lighting a gas lamp or cooker in the tent if it is safe to do so.
Build a fire. There are so many ways to do this, so try them out when it matters.
