What Is an Inventory Control System?

An inventory control system is a software used in logistics sites to monitor and control the quantity of products in stock in real time.

It centralizes all processes necessary for business operations, such as inventory control system, ordering system, and sales management in factories and stores, thereby improving work efficiency.

Appropriate inventory control systems are proposed for different industries, such as retail, trading, and manufacturing. Furthermore, based on the basic package, in many cases, additional options can be added in a flexible manner.

Uses of Inventory Control Systems

Inventory control systems are used for different purposes in different businesses.

1. Uses in the Retail Industry

In the retail industry, the inventory in the inventory control system changes at the same time as the check is settled at the store. In this case, the accounting system and the inventory control system must be linked. By setting an order point for each product, it is possible to place an order automatically when the quantity falls below the order point.

In addition, retailers with online stores can manage inventory in real time to determine whether to accept orders according to inventory status. Taking an order despite a lack of inventory can lead to problems.

2. Applications in the Food Industry

In the food industry, managing delivery deadlines necessary for freshness control, such as expiration dates of food products, enables first-in, first-out (FIFO) operations. By managing the use of old items first, it is possible to reduce the amount of waste due to expiration of expiration dates.

It also leads to the understanding of distribution information (traceability) of purchased food products, making it easier to control the origin and the source of purchase.

Uses in the Manufacturing Industry

In the manufacturing industry, managing the number of parts in stock can help prevent problems with missing parts. If a necessary part is found to be missing at the start of production, it can lead to reduced productivity and delivery delays.

By knowing the quantity of parts required for production in advance, you can order the missing parts.

Principle of Inventory Control Systems

An inventory control system is used to receive and pay for the quantity of items to be controlled. Receiving means “receiving” when something comes in and “paying” when something goes out.

In the manufacturing industry, for example, the quantity of parts in the system is increased when the parts for manufacturing are delivered to the factory. The quantity of parts in the system decreases when the parts are shipped out after manufacturing is completed.

An inventory control system automatically manages these positive (receipt) and negative (payment) transactions, but the timing of receipt and payment depends on the system and the company’s management policy. Inventory control systems also have the ability to adjust inventory quantities to the optimum level.

This is useful for cases where you want to keep a sufficient amount of inventory or when you only need what you need when you need it. By configuring your inventory control system according to your purposes, you can make the most effective use of it.

Other Information on Inventory Control Systems

Importance of Inventory Control Systems

An inventory control system is software that manages a store’s inventory from sales and manufacturing to accounting, streamlining the entire process. Sales, manufacturing, and accounting are the central activities of a company and are referred to as core systems.

While there is no problem if the core system is properly operated by book inventory with no discrepancy from actual inventory, it is seen that book inventory and actual inventory do not match. In particular, the more complex inventory management becomes, such as when multiple stores are involved, the greater the risk of such discrepancies from actual inventory. Proper inventory management is necessary to prevent overstocking.

Inventory control systems are powerful tools for accurately tracking physical inventory. It eliminates the need for time-consuming data entry, reduces processing errors, and provides a real-time, accurate picture of inventory.

It also allows for easy reference when searching for past products. In recent years, cloud-based systems have been on the rise, further advancing remote management.

What Is a Sterilizer?

A sterilizer is a device that can sterilize food and other objects. Sterilizers can be broadly classified into ultraviolet (UV) sterilizers and high-temperature, high-pressure sterilizers.

UV sterilizer, which uses ultraviolet light for sterilization, has the advantage of causing little damage to the object and preventing the development of resistant bacteria. However, since it can only sterilize the surface where the ultraviolet rays hit, it is not effective enough if something blocks the ultraviolet rays.

High-temperature, high-pressure sterilizers heat and sterilize food under high-temperature, high-pressure conditions to shorten the time required for sterilization. Unlike autoclaves, which are a similar type of sterilizer, this device has a cooling function, effectively minimizing the cooling duration.

Uses of Sterilizers

Sterilizers are used for the purpose of hygiene control and contamination prevention. They are used in a wide range of fields, including chemicals, pharmaceuticals, and precision products. They are especially indispensable in the food industry, where contamination by harmful bacteria is not permitted.

Typical applications in the food industry include sterilization of retort pouch foods, such as canned and bottled foods. In vacuumed foods such as canned and bottled foods, “botulism,” a bacterium that hates oxygen, can easily multiply.

Botulinum is a well-known toxin-producing bacterium that can cause food poisoning, so careful sterilization using sterilizers is necessary when manufacturing the above foods.

Principle of Sterilizers

There are two main types of sterilizers: high-temperature, high-pressure sterilizers and ultraviolet sterilizers.

High-temperature, high-pressure sterilizers, are used to sterilize harmful bacteria, including botulism, contained in food products. Botulism is known to protect itself by forming heat-resistant “spores,” and must be sterilized by heating to a sufficient temperature and time. Food safety can be maintained by using high-temperature, high-pressure sterilizers to sterilize food under strict conditions equivalent to 120°C for 4 minutes.

There are two types of high-pressure sterilizers: steam type and hot water type. The hot water type is further divided into hot water storage type and hot water spray type. In the hot water spray type, hot water is sprayed to create a high-temperature, high-pressure atmosphere in the sterilization tank, thus preventing uneven temperatures.

The second type of sterilizer is the ultraviolet sterilizer, which irradiates the object with ultraviolet rays. Irradiation with ultraviolet light can destroy the cell membranes of bacteria, resulting in their death.

Mercury and ozone lamps are the main sources of ultraviolet light used in sterilizers. By employing these lamps, it is possible to irradiate ultraviolet rays with a wavelength (UV-C region) that is easily absorbed by cell membranes and has good sterilization efficiency.

What Is a Disc Spring?

A disc spring is a spring with a conical shape, resembling a bottomless dish with a hole in the center. It compresses under an external load and returns to its original shape, making it essential for various mechanical applications.

Applications of Disc Springs

Disc springs, capable of carrying high loads in compact spaces, are used across various sectors. They find applications in automotive clutches, hydraulic pistons as return springs, vibration isolators for press machines, and for applying preload in hinges and bearings, ensuring smooth operation and reducing slack.

Principle of Disc Springs

The functionality of disc springs is based on elastic deformation, where the conical part bends under pressure, creating a spring force. This principle allows disc springs to support compressive loads effectively, in contrast to coil springs, which are designed for compression, tension, and torsion applications.

Main Characteristics of Disc Springs

Key features of disc springs include their compact design that allows for high energy storage with minimal deformation, and their ability to adjust load and deflection through stacking. However, variations in manufacturing can affect the performance of stacked springs.

Other Information about Disc Springs

Stacking disc springs in series or parallel configurations allows for the customization of spring characteristics to meet specific requirements. Series stacking increases the load capacity, while parallel stacking increases deflection. Additionally, the difference between disc springs and disc spring washers is highlighted in their applications, with disc springs designed for dynamic loads and disc spring washers used to prevent bolt loosening under static loads.

What Is an Oxygen Generator?

An oxygen generator is a device that extracts high-purity oxygen gas from the air by separating nitrogen and other gases. These devices leverage adsorbents for gas separation, offering a cost-effective and scalable solution for oxygen supply without the need for high-pressure storage.
