Pumpkin is composed of criss-crossing vascular bundles, mostly oblong, slightly thinner at both ends, with a diameter of 5- 10 cm, varying in length, yellow-white and rough surface, sometimes with residual peel and pulp, light weight, toughness and elasticity, three cavities in cross section, and occasional black seeds. A slight breath, a faint taste. It is best to be large, complete, clean, tough, yellow and white and seedless.
Other uses:
1, Luffa sponge has strong water absorption capacity and is a good material for insoles. After professional design and processing, loofah has been used in bath, foot health care, decoration, toys, cushions and other fields.
2. Some oil-bath air filters used in diesel engines use corrugated thin iron wires as filter elements. Due to the impact of high-frequency and high-speed pulsating airflow, the iron wires rub against each other and gradually break into iron filings, which fall into the oil pan, and the filter element becomes thinner and looser, and the filtering effect decreases. If the filter element is not repaired in time, the air filtration effect will deteriorate sharply, leading to the rapid wear of piston, piston ring, cylinder, valve and valve seat.
In this case, the fresh dried loofah can be peeled and seeded, cut into strips and put in a filter tray. It is elastic and has reticular gaps, which can play the same filtering effect as iron wire.
3. Mature loofah can be used as a kitchen cleaning rag, which is environmentally friendly and low-carbon.
