1. 1 juicer by type:

Manual juicer: juicing by manual squeezing and rotating, etc., without electricity, low price, time-consuming and laborious.

Electric juicer: The food is crushed by the rapid rotation of the electric-driven blade and knife net, and then filtered by the filter screen to form juice.

Juicer: Squeeze the juice with a screw at a slow speed. Because the rotation speed is mostly below 100 rpm, it is also called low-speed juicer.

Wall-breaking machine: also known as wall-breaking machine and mixer. The essence is the same as that of the electric juicer, except that the motor power is stronger, and the rotating speed of the blades is generally above 20,000 rpm, which can fully crush the mixed ingredients and can be directly drunk without a filter screen.

Orange juice machine: squeeze citrus juice vertically through conical filter. Although the pretreatment is simple, the function is too simple, and only citrus fruits can be extracted. There are few domestic households, mainly concentrated in the commercial field.

1. 1 juicers are classified according to their working principles:

Centrifugal juicer: The juice is driven to rotate by the rapid rotation of the blade and the knife net, and the generated centrifugal force makes the juice stick to the outer wall of the barrel-shaped filter screen, and the liquid juice passes through the filter screen due to the centrifugal force, and the pomace remains in the filter screen.

Squeezing juicer: There is no blade design, but blunt tools such as screws and cones are used to squeeze and grind the ingredients through the filter screen.

Mixed juicer: First, the ingredients are filtered by extrusion, and then the purer juice is obtained by centrifugal separation.

Blender: The principle is the same as that of centrifugal juicer, except that there is no filter screen, and the motor rotates at a higher speed, completely breaking the ingredients.

2. Technical terms of juicer

2. 1 Can the wall breaker really break the wall?

The answer is yes, but in fact, it is not just a broken wall machine, any juicer can break the wall. In fact, the main component of juice is vacuoles in plant cells, which are all wrapped by cell walls. If we can't break the cell wall, then we can't drink juice.

2.2 Which juicer can better retain the nutrients in the fruit? Is it a blender?

Compared with the common juicer, the juicer juiced more thoroughly, wasted less fruit and obtained more nutrients, but the dietary fiber and other nutrients in the pomace were discarded. From the nutritional point of view, the wall-breaking machine retains the most nutritious components of the fruit.

2.3 What is a portable mixer?

Portable mixer is a fresh form, and its essence still belongs to the wall-breaking machine (mixer). It has the characteristics of fast speed, sufficient nutrition retention and easy cleaning. You can also take off the blender cup and buckle the lid as a portable cup to drink juice anytime and anywhere. However, compared with the common wall-breaking machine, the portable mixer has less power and capacity and can only stir fruits and vegetables.

2.4 Is drinking fruit juice healthier than eating fruit? Can I use juice instead of eating fruit?

Fruit juice mainly retains minerals and moisture in the fruit, as well as sugar that everyone can't avoid now, while most dietary fiber is thrown away as pomace. More importantly, dietary fiber needs gastrointestinal peristalsis to be digested (so dietary fiber can also promote gastrointestinal peristalsis), while juice with less dietary fiber digests faster, which means that sugar is more easily absorbed by the human body. In addition, vitamin C contained in fruit is easy to be oxidized and lost, which is inevitable when squeezing juice. Even the wall-breaking machine that keeps the pomace will lose the nutrition of the fruit due to factors such as stirring and machine heating. So the healthiest way is to eat fruit directly. As for juice, enjoy it as delicious.

2.5 How to choose several juicers?

Juicer:

1. Price: low (1000 yuan or less, low-end models below 200 yuan); 2. Juice taste: moderate taste; 3. Juicing speed: slow; 4. Juice yield: low; 5. Noise: loud; 6. Squeezable ingredients: suitable for crisp and moist fruits and vegetables, and the juice yield of soft fruits such as oranges and watermelons is low; 7. Cleaning difficulty: pomace will remain on the surface of the filter screen, which is very troublesome to clean; 8. Pretreatment difficulty: it needs to be washed and cut into pieces without peeling and coring; 9. Nutrition retention rate: low;

Juicer:

1. price: medium (about 500-2000 yuan) 2. Juice taste: the best taste; 3. Juicing speed: slow; 4. Juice yield: high; 5. Noise: small; 6. Squeezable ingredients: the effect of squeezing soft fruits is also very good, and the screw material can also squeeze sugarcane; 7. Cleaning difficulty: pomace will remain on the surface of the filter screen, which is very troublesome to clean; 8. Pretreatment difficulty: the discharge port is smaller than the juicer, so it needs to be cut into smaller pieces without peeling and coring; 9. Nutrient retention: more thorough extraction than juicer, retaining more nutrients;

Wall breaker: 1. Price: higher (1000 yuan or more); 2. Juice taste: special taste, similar to puree; 3. Juicing speed: faster; 4. Juice yield: all ingredients are broken, and there is no juice yield; 5. Noise: maximum; 6. Squeezable ingredients: The characteristics of stirring are most suitable for bananas, avocados and other ingredients. You can also crush ice to make smoothies, grind soybean milk, meat, dry powder and so on. 7. Cleaning difficulty: cleaning is the simplest, just add water to the cup and idling; 8. Pretreatment difficulty: it needs cleaning, coring, peeling and dicing; 9. Nutritional retention: pomace also becomes a part of fruit juice, with the most nutritional retention;
