Grape juicer

Types of Grape Juicers

Grape juicers are essential equipment for extracting juice from grapes. They can be categorized into industrial, commercial, and home-use grape juicers based on their applications.

• Industrial grape juicer machines

  Industrial grape juicer machines are large machines capable of processing large volumes of grapes at a time. These machines are typically very powerful, and they come with several juicing functions. More advanced industrial grape juicers may even have automation functions for automated feeding, juicing, and bottling processes. These machines are mostly used in industrial settings where huge quantities of grape juice are required to meet high demands. They may also be used for export or in production lines that require grape juice as an ingredient.

• Commercial grape juicer machines

  Commercial grape juicer machines are powerful machines used mainly in commercial settings, such as restaurants and cafes, to extract grape juice for sale or for use as an ingredient in other products. They can process grapes faster than typical home-use juicers, but they aren't as big or powerful as industrial grape juicer machines. Some commercial grape juicers also come with added features, such as multiple juicing modes, in which users can choose to extract juice with or without pulp. Some also have separation systems for separating the skin of the grapes from the juice.

• Industrial grape juicer machines

  Industrial grape juicer machines are the regular-sized juicers that most people can use at home. They are smaller, compact, and lighter so that users can easily move them around and store them when not in use. Like their commercial counterparts, home-use grape juicers may come in different types, such as centrifugal grape juicers, cold press grape juicers, and steam juicers.

  Centrifugal grape converts the grapes into juice via century force. The grape is ejected into a mesh strainer, where the juicer’s blade spins super fast to separate the juice from the skin. These types of juicers are usually very fast, but the juice extracted doesn’t taste very great.

  Cold press grape juicers extracts juice from grapes by first grinding them into a pulp and then squeezing out the juice. They are a great choice for people who want to extract grape juice that tastes great. Unfortunately, they tend to be slower than their centrifugal counterparts.

  Steam juicer grape extract juice from grapes using steam. They are quite easy to operate, and they usually produce pure grape juice with no preservatives or added ingredients.

Specification and maintenance of grape juicer

Manual grape juicer

• Material: Manual juicers are typically made of food-grade stainless steel, cast iron, or aluminum. Which materials are chosen will directly impact the overall quality and performance of the product.
• Size: The size of a manual grape juicer can be represented by the whole juicer's dimensions or its pressing mechanism, such as a press bucket diameter. For example, a common bench-type manual grape juicer's dimensions are 380 x 380 x 600 mm.
• Weight: Many manual grape juicers are not very heavy, so they are more portable than electric ones. The weight of a common juicer is about 5 kg.
• Harvest method: Manual grape juicers have different ways to extract juice. Some models first crush the grapes and then squeeze them for the juice; others directly squeeze the whole grape for the juice extraction.

Electric grape juicer

• Motor power: The power of an electric grape juicer motor determines its juice extraction efficiency and ability to handle different quantities of fruit. For industrial use, a higher power motor is usually required, and small electric juicers for household use have motor power between 200 and 800 W.
• Production capacity: Electric grape juicers can process large quantities of grapes in a short time. For example, an electric grape juicer can produce about 1,000 to 1,500 ml of juice per minute. That means users can extract the juice of around 10 to 15 kg of grapes in one minute.
• Material and size: Like the manual juicer, electric grape juice extractors are made from different materials and come in varying sizes.
• Noise: Electric grape juicers produce varying noise levels when working, depending on their motor power and design.

Maintenance

• Clean thoroughly: Cleaning the electric grape juicer is the most important maintenance step. Disassemble the parts that can be disassembled and rinse them thoroughly. Use a brush to clean the outlets and crushing parts, and wipe the remaining juice with a cloth.
• Dry: After cleaning, dry the juicer thoroughly to prevent moisture and mold. If it is made of metal, it can prevent rusting.
• Lubrication: Regularly lubricate the moving parts, such as bearings and rotating shafts, for smooth juice extraction.
• Avoid overloading: Be careful not to overload or overuse them to protect the motors and internal parts, which can extend their service life.
• Keep it ventilated: Place the electric grape juicer in a well-ventilated and dry location during storage. Avoid exposure to sunlight for a long time or close to heat sources.
• Regular checking: Regularly check the grape juicer, ensuring the motor, wires, and juice outlet are in good condition and there is no abnormal noise or leakage.

Applications of grape juicers

The primary function of the grape press juicer is to extract juice from grapes. However, different types of grape juicers offer various applications and uses. Here are some of the uses of grape juicers.

• Wine making: The traditional grape crusher is mostly used for winemaking. When the grapes are crushed, the juice is extracted and fermented by yeast into wine. The fermentation process adds flavor and creates alcohol content in the beverage. Even though industrial winemakers use large machines to crush grapes for wine, some small-scale winemakers still use the traditional grape juicer for crushing.
• Juice making: Many food-processing companies use large-scale grape juicers to make grape juice, which they package in bottles and ship to supermarkets and convenient stores. Grape juice is considered a healthier beverage option and is sometimes used as an alternative to soda for children.
• Smoothies and Mixed drinks: Many bars and restaurants use smaller grape juicers to produce fresh grape juice that can be mixed with other ingredients to make cocktails and smoothies. Beverages made with freshly squeezed juice tend to have fuller flavors compared to those made with bottled juice.
• Health and Nutritional supplements: Natural grape juice extracted from grape juicers is often used as an ingredient in nutritional supplements. Grapes are rich in antioxidants and other vitamins beneficial to health. Private-label suppliers may utilize grape juicers to produce pure grape juice that contains no additives or preservatives. They then package the juice into bottles and sell them as nutritional supplements.
• Cosmetic products: Grapes contain resveratrol, an effective ingredient that helps prevent skin aging. Many cosmetic companies use grape juicers to extract grape juice that contains this powerful antioxidant and include it in their anti-aging products. These products may include moisturizers, serums, and face masks, among others.
