Humidification solution for production workshop

Ensuring Optimal Conditions in Electronic Workshops

In today’s competitive landscape, electronic workshops are facing increasingly stringent quality control standards. To maintain high product quality, it is crucial to carefully manage temperature and humidity levels within the production environment, with particular emphasis on humidity control. Excessively dry conditions can lead to static electricity buildup, which poses a risk to sensitive components like CMOS integrated circuits. For instance, tests have shown that at a relative humidity of 20% RH, static voltages can reach up to 10,000V, and at just 10% RH, this can escalate to 20,000V.

Moreover, overly dry air contributes to airborne dust, which can aggravate respiratory issues and negatively impact the health and well-being of workers, ultimately affecting overall productivity. Ideally, electronic workshops should maintain a temperature of approximately 22°C and a relative humidity level between 40% and 60% RH. This range not only creates a comfortable working environment but also minimizes static electricity concerns.

During winter months, when outdoor air tends to be less humid, it becomes essential to incorporate effective humidification strategies. For example, if an electronic workshop is designed to refresh indoor air twice per hour—ensuring adequate oxygen levels—it’s important to note that while increased air changes can enhance oxygen content, they also necessitate greater humidity control.

Solutions for Fruits and Vegetables Preservation

Factors affecting the preservation of fruits and vegetables

The metabolic activity and storage effectiveness of fruits are influenced by two primary categories of factors: external conditions and intrinsic properties of the fruit itself. Key external factors include temperature, gas composition, and humidity. Lower temperatures can inhibit fruit respiration and other metabolic processes, effectively delaying the aging process. To maximize storage life without causing chilling injury, it is essential to utilize the lowest possible temperature.

The composition of gases in the storage environment also significantly impacts fruit preservation. By modifying the gas composition—such as lowering oxygen levels and increasing carbon dioxide concentrations—it is possible to slow down metabolic rates and extend storage time. Additionally, after harvesting, fruits cease to absorb water from their roots, leading to structural, textural, and surface changes. Therefore, maintaining appropriate humidity levels and minimizing water loss are critical for preserving the freshness and quality of fruits.

To combat humidity-related challenges in fruit and vegetable preservation, ultrasonic humidifiers are widely used in large supermarkets. These devices help keep produce fresh by maintaining humidity levels, reducing water loss, and preserving the vibrant color and quality of fruits and vegetables.

At STH, we specialize in developing and selling a range of dehumidification solutions, including household, commercial, and industrial dehumidifiers.

Solutions for Fungus planting

Fungus planting humidification solution

The spray humidifier designed for edible fungus cultivation helps to increase air humidity, creating a more conducive environment for mushroom growth. Edible fungi thrive in humid conditions, and dry air can adversely affect their growth rate and yield. Therefore, it is essential to humidify the mushroom house to boost air humidity, which in turn promotes the development of edible fungi and enhances the efficiency of mushroom farmers.

Many growers mistakenly believe that humidity control is only necessary during the fruiting stage of edible fungi, often neglecting humidity management during the mycelial growth stage. This misconception is common among both novice cultivators and some commercial mushroom producers, who may overlook the importance of maintaining humidity levels during the germination phase.

In the production of edible fungi, conventional water management practices have evolved. Instead of using regular water during the mushrooming period, the use of magnetized water for spraying has been adopted. This method has shown significant benefits for various edible fungi, including oyster mushrooms, phoenix mushrooms, shimeji mushrooms, enoki mushrooms, coprinus comatus, shiitake mushrooms, and hericium erinaceus. By applying this technique during both the sprouting and fruiting stages, growers have reported an average yield increase of 20% to 30% compared to traditional water spraying methods. This approach not only enhances the appearance and color of the mushrooms but also improves overall product quality.

Solutions for tobacco industry

Ensuring Optimal Moisture Levels in Tobacco Leaves

The issue of moisture regain in tobacco leaves is a significant concern for farmers. Insufficient moisture can cause leaves to become dry and fragile, complicating their transportation. In the tobacco industry, leaves are graded, and maintaining the appropriate relative humidity is crucial for producing high-quality tobacco. The completeness of the leaves is a key indicator of their market value; incomplete or damaged leaves can lead to lower prices. So, how can this challenge be effectively addressed?

To preserve the integrity of tobacco leaves, it is essential to reintroduce moisture. There are generally two methods for adding moisture: the natural moisture regaining method and the use of a tobacco leaf moisture regaining machine. The natural method involves opening doors and windows in the curing house or warehouse during the evening to allow natural humidity to permeate. However, this approach is time-consuming and can be affected by regional and environmental factors.

Many tobacco farmers opt for tobacco leaf moisture regaining machines, which can significantly reduce the time required for moisture regain. Natural methods typically take 6-7 hours, and even longer in dry conditions. In contrast, moisture regaining machines operate independently of weather, ensuring efficient moisture restoration. If the leaves dry out again after initial treatment, the machine can be used anytime to maintain optimal moisture levels, preventing fragility. Additionally, these machines offer convenient operation, excellent atomization effects, and save both time and labor.
