Fruit crushing (milling or mashing) is the first size-reduction step in juice and pulp production, breaking the fruit tissue to release juice or facilitate enzymatic and pressing operations. The appropriate crusher type depends on the fruit: hammer mill crushers (rotating hammers reduce apple, pear, quince, and other hard pome fruits to a fine pomace for subsequent pressing — the fineness of the mash affects juice yield and quality); roller crushers (coarse rollers crush soft fruits and grapes, releasing juice without over-grinding); centrifugal mills (high-speed rotating elements crush soft fruits); grape destemmers and crushers (remove stems and gently crush grapes before pressing or fermentation — destemming reduces tannin extraction from the stems in wine production); and tomato crushers (break tomatoes before pulping and paste processing). The degree of size reduction (fineness of the mash) affects juice yield, clarity, and the required pressing force — finer mash typically gives higher yield but more suspended solids and pectins in the juice.
Frequently asked questions
Why is pomace particle size important in apple juice production?
In apple juice production, the fineness of the apple mash (pomace) produced by the crusher significantly affects juice extraction yield and juice quality. Finer pomace has higher surface area, releasing juice more easily during pressing and producing higher yield from a given mass of fruit. However, over-fine mash can produce a dense, compressible cake that is difficult to press and drains poorly. Most commercial apple mill crushers produce a controlled particle size that is matched to the belt press capacity. The mash particle size may be adjusted by changing the screen or the rotor speed of the hammer mill. Enzymatic treatment (pectinase) of the mash before pressing further improves yield by degrading pectin in the cell walls.
What is the difference between a grape crusher and a grape destemmer?
A grape crusher gently breaks the grape berry to release juice, without extracting seeds or breaking the skin excessively (which would add harsh tannins to the must). A destemmer removes the stems (rachis) from the grape bunches before or after crushing — stems contain bitter, harsh tannins that, if included in the fermentation, would produce an astringent wine. Most modern winery equipment combines both functions in a destemmer-crusher (or in some winemaking styles, a crusher-destemmer where crushing happens first). The order of destemming and crushing affects the style of the wine. For fruit juice production using grapes, destemming and gentle crushing before pressing minimises tannin and harshness in the juice.
